[FR] Support for 4Max Pro 2.0 (and original 4MP)

[alfrankgit]

Hi! I really appreciate the effort you put into the Anycubic Mega Firmwares, since Anycubic doesn't do anything.

How about supporting the 4Max Pro (2.0 and original version) also? They have the same boards and displays.

For the 4Max Pro 2.0 I already patched your V1.1.9 in the Mega P TMC sections, see the attached Configuration.h and Configuration_adv.h. It has a BMG clone extruder, TMCs for X and Y, other thermistors. I had to disable the Anycubic Filament Sensor option.

I commented all my changes with //AFR.

But I am no programmer so I can't add a new environment to your project. But that would be nice to have, wouldn't it?

I also have three of the original 4Max Pro but none still in the original configuration, so I'm not sure what that was. IIRC it doesn't have TMCs and it definitely has the original DWIN display. But it has the Titan clone extruder. And hotend thermistor type 11. But I can test a configuration for that one too, if you can create an env for it.

PS: My native language is German.

Edit, 26.01.2021: made a few changes in speed and acceleration settings, reuploaded changed files...

4MP_2.0_KW1.1.9.zip

[knutwurst]

Hello, so since the hardware seems to be the same, that wouldn't be a problem and I think it's great that you have already done the preparatory work :)

But I'm currently working on support for the Chiron - and by that I also mean support for all display functions, including leveling. There is also very strong demand for support for the Mega Pro Laser.

I'll see how quickly it goes with the 4MAX Pro, but I can't promise that I can take care of it right away. But I'll write it on my agenda :)

[alfrankgit]

Hi, and thanks a lot for your reply and infos.

As a moderator on drucktipps3d.de I'd gladly welcome you to our forum where I already recommended your excellent firmware quite a few times.

[knutwurst]

I've included the 4MAX pro 2.0 build environment for stock and TMC. I actually don't know if all motor directions are correct, so please give me some feedback, what's not working correctly KW-131-4MAXPRO2.zip .

[alfrankgit]

Thanks for including the 4Max Pro 2.0 now, but I can't test it myself anymore because I don't own the 4Max Pro 2.0 anymore. But there are users on drucktipps3d.de who do and are aware of your firmware and my "hacks". https://drucktipps3d.de/forum/topic/anycubic-4max-pro-2-0/?part=23#postid-180447

[knutwurst]

@alfrankgit Maybe you can shed light on the darkness. I saw in your config that you are using the Build Environment of the MEGA_P and activate both MEGA_P, TMC and DGUS2 for it.

Are these settings for the stick 4MAX or for one in which all drivers have been substituted for TMC2208?

If you built MEGA_P_TMC for the 4MAX stock, I had a mistake in thinking and maybe the directions of the two versions (TMC and non-TMC) are now reversed :D

I'm looking forward for some "testers" ;)

[alfrankgit]

I didn't change any physical stepper drivers on the 4Max Pro 2.0. All my changes in the configuration files are marked with //AFR, either as a new comment to disable a line or as a comment with the original content of the line followed by a line with the changes I made.

[knutwurst]

...then... the 4MAX_TMC version should work on stock. Let's wait for feedback.

And thank you again for your provided config!

[JonnyHaystack]

I've been using alfrank's config with MEGA_P_TMC environment. I can test with the new environment at some point :smile:

[knutwurst]

After getting some feedback I added configurations for both, Stock and full TMC Versions. Now also for the original 4MAX Metal. The case light (controllable via touchscreen) should also work. Please let me know if there are any other issues. If not, I'll release the version in the upcoming days.

KW_4MAX_4MAXPRO2_v1.3.1.zip

I'm new to this thread and have limited experience with marlin but I tested your hex files currently I have found the file titled (4MAXP2_v1.3.1-4MP2) to work but with 2 glitches. I don't know if these glitches are unique to my machine 4maxv2 or in the firmware itself. The display will run two intro cycles on startup and the stop print button will flicker until the tool head is parked.

I hope this info is of anyhelp.

[MasterYod4]

Hello first of all, I would like to thank you very much for your work! I tested version 4MAXP2_v1.3.1-4MP2 on my 4Max Pro 2.0. What I noticed is that the light button now works but the normal 4 point leveling in Anycubic Menu doesn't work. As described by q4wey, the intro runs twice but I couldn't detect the stop button flickering.

Yes, same for me (tested 4MP2 stock version). The original "Leveling"-Button isn't working (like in the self compiled versions before).

@MasterYod4 You can go to "print" -> "Special Menu" to get 4 point or even Mesh bed leveling.

[MasterYod4]

@CruisenRainerWahnsinn Thanks for the hint.

[knutwurst]

The original "Leveling"-Button isn't working

I know... that's because it's not implemented at all. I just included the build paths and ne configurations and "hacked" the light control in. This isn't final at all. It's just a milestone. I'll take a look at anycubic's implementation of the leveling menu. If it's straight forward, i'll implement it also.

In the meantime, you can use the specialmenu like @CruisenRainerWahnsinn mentioned :)

[JonnyHaystack]

Is the filament runout sensor working? I think some other people may have got it working in forks that I've seen

[knutwurst]

@JonnyHaystack it's currently disabled until I figured out the correct pin.

[hanebuechenes]

Tested the version KW_4MAX_4MAXPRO2_v1.3.1.zip on stock 4max V1. seems to work nice, only the Y axis is wrong direction. Can i change this somewhere, or have it to be compiled again?

Which hex file did you chose of the zip? There are 4 files.

I'm not sure if it is true for the 4max (1), but if you use TMC Version of 4MP2 the direction is switched. So the TMC version of it might fix this issue.

[MasterYod4]

I played around a bit today and noticed the following:

Set flow rate - works Preheat Ultrabase - works 4 Point Leveling - only drives up to point A, all other points are not approached Mesh leverling - works PID Tune Hotend - does not work PID Tune Ultrabase - works

[Yury-MonZon]

I second what MasterYod4 said.

Also, I've tried both TMC and non-TMC version on 4Max Pro 2.0(which has TMC installed by default). TMC version has Z axis reversed.

On both versions I can't read/send commands via USB, I've tried 57.6k, 115.2k and 250k baudrate - got corrupted data. The cable and drivers are fine - I can successfully flash the board. And I can connect to the stock firmware with 250k baudrate.

Stopping the printing process from the touchscreen shows me like a thousand of popup screens that stop is done. It doesn't happen if I pause the print and then stop it.

I'm able to test multiple times, if it could be useful to developer - let me know.

[Daventrik]

i would be glad to help with testing but i didn't flashed my printer with these versions yet, still on stock but i have the "round corners" on a square and i hope that the new firmware can solve that issue since the profile tuning is not solving this. How can i help?

[knutwurst]

1.4.0 Beta 2 is out now.

Try setting K factor to 0.2

Send "M900 K0.20" and safe with M500 Try 190°C (if PLA) Get a e3d V6 nozzle (fits on stock hotend) => big improvement

[q4wey]

1.4.0 Beta 2 is out now.

Tested 1.3.0 beta 2, didn't make any changes just complied and uploaded. No menu pops up in the print menu for mesh leveling etc. Motors are all in the correct direction and homes/ heats up.

I will buy a e3d v6 nozzle but what would be recommended? Brass? copper plated, stainless steel? Thank you!

[Yury-MonZon]

Version 1.4.0.-b2 doesn't have linear advance support on 4Max Pro 2: Unknown command: M900 What about thermistor type, is it correct? I had to raise the nozzle temp to 230 for PLA to get proper layer adhesion (with 70% part fan as mentioned in the guide). Is it wrong or it is happening because of the stock steel nozzle? Thanks a lot!

[knutwurst]

4 Point level fixed in b6a11d2 PID Tune fixed in 9cbf70c Linear advance fixed in dd169b7

Thanks for your feedback!

[Yury-MonZon]

You are the man! That was quick! Thanks a lot! Are you planning to release 1.4.0-beta.3 with those fixes any time soon?

[q4wey]

@knutwurst

Tested the new release 1.4.0.beta 2 today. When using the built in remove filament tool while a print is paused the filament will begin to remove but then the printer reboots so you cant resume the print.

Your doing great work on this mate, many thanks.

[knutwurst]

@Yury-MonZon dunno... I have to fix some more things as you can see ;) In the upcoming days I think. But you can check out the master branch and compile it by yourself :)

@q4wey Does this only apply to the 4MAX Pro v2?

[CruisenRainerWahnsinn]

Didn't test the latest alphas yet. Still very happy about 1.3.1 :) already

Concerning ENV and 4max types: There are several 4max out. Just wondering if env "4max" is meant to be "4max pro (1)". There should be 4max, 4max pro, and 4 max pro 2 (afaik)

Concerning acceleation/jerk parameters that are working very nice for me:

Recv: echo:; Steps per unit:
Recv: echo: M92 X100.00 Y80.00 Z800.00 E423.50
Recv: echo:; Maximum feedrates (units/s):

: (changes on the printer: e3d V6 nozzle and adapted fan duct)

[knutwurst]

@CruisenRainerWahnsinn take a look at the Beta (not alpha). ;) All 4MAX variants should be covered. Beta 3 is on the way with more improvements.

I'll check them out 100%. Thank's a lot for your work!

[Yury-MonZon]

@CruisenRainerWahnsinn Print acceleration 1500? Looks a bit high to me, how did you get rid of the ringing? What are your print speeds with these settings? Also, how did you manage to install e3d v6 nozzle? It is longer, isn't it?

It's working great for me with these setting.

This is the latest Cura Profile I'm using (from the print you see): https://www.dropbox.com/s/qxn14x4ppobsnq3/4MaxPro2.0_PLA_0.2mm_192C.curaprofile?dl=0

The only thing you need to adapt to the e3d v6 nozzle, is the height of the fan duct (needs little sanding or reconstruction). The e3d v6 nozzle fits the stock hotend perfectly. + I prefere capricorn tube.

There is still a tiny tiny bit of ghosting going on, but it's very hard to see and ok for me.

I got trouble on Z-Axis at 180mm. I put some grease on the z-axis, went up and down and made 2 test prints (2 towers 5*190mm). First one was better than prints i did before. Second test print worked fine - no more rough layers on the top of the prints.

@q4wey Does this only apply to the 4MAX Pro v2?

yes my apologies this was tested on the 4max pro 2.0 i should have specified

[q4wey]

Tested 4MAXP2_DGUS_v1.4.0-b3.hex on the 4max pro 2.0. When printing and the pause button it pressed a message of SD pullout will pop on the screen until the printer head it parked. after the head is parked 3 beeps are made but when you try to resume the print it just wont resume.

[Yury-MonZon]

it just wont resume

I also have this sometimes. Wondering why is this not a constant thing?

[knutwurst]

@q4wey and @Yury-MonZon are you sure that you have the DGUS variant with Anycubic 0.0.2 Display? There is a Pause/Resume bug in the original DGUS II.

[Yury-MonZon]

I'm sorry, didn't know that they are different. How do I get the model of the screen?

Thanks a lot.

[luknz]

Hi, first of all thank you very much for your effort! Knutwurst has been running flawlessly on my i3 Mega for months. Today I also flashed my Anycubic 4Max Pro 2.0 with V 1.4.0-beta.3. Since then he has been making strange whistling noises when printing, like an old Internet modem. Does anyone know what could be causing this?

Update: I have since found out that the beeps and whistles are triggered by the start code from github. The noises only appear when I print with the suggested start code (https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/wiki/Cura-Start--and-Endcode-with-preheat-and-purge-line). If I use the standard Cura start code, the printer prints quietly as usual.

[Truggy]

Not sure what I did wrong. I have v002 board 4mp v2.

when I stop a print the system crashes and is ina continuous reboot until hard switch is switched off.

I have the clone screen as well - same behavior with stock steppers or all tmc 2208. Did reset and load defaults in eprom.

thanks, John

[Yury-MonZon]

continuous reboot until hard switch is switched off

When I do this I have multiple messages on the screen. So I use pause and then stop. And after that printer doesn't print when you start a new print.

[Truggy]

That the same as I have. Ok. Wasnt sure if something was up with the mainboard.

[dspitzer]

After a lot of fiddling I managed to install a BLTouch in the 4Max Pro 2 and with the latest master the auto levelling works perfectly - thanks a lot @knutwurst !

I'm using the 4MAXP2_DGUS_BLT_10 and the only parameter that I changed was the NOZZLE_TO_PROBE_OFFSET.

A few quirks that I noticed so far: After booting, the display immediately reboots (it basically shows the startup animation twice). Also, stopping a print results in a boot loop - I have to turn the printer off every time I stop a print.

[Truggy]

I get the same but I used the non blt firmware.
