MKS SBASE - Lost steps in Y and random BLTouch deployment

[gauix4]

Hello brand new still this problem Marlin no compilation problem stepper well settled no problem after a while there is offset in Y... 100% sure it's a Marlin problem with other map everything works fine 1 - the BLtouch tends to deploy itself 2- the Y always shifts after a while

I use atom as a compiler

[gauix4]

we see that there is a problem because the temperature varies by itself

[gauix4]

[p3p]

If you run pio update in the atom terminal what version of framework-arduino-lpc176x are you running,

Always supply the information requested in the issue template, such as full configs. additional information about your hardware setup may also help us rather than just specifying that things that don't work.

[gauix4]

[p3p]

did framework-arduino-lpc176x update when you ran pio update or were you already on 0.0.5?

[gauix4]

@p3p this one was not showing at all this is the first screen shot I made by sending the command

[gauix4]

but I think that's it there were a lot of things that were not up to date that went on as the best way to know is that i re test ^^

[p3p]

I know that's why I asked, it hadn't finished at the point you took the screenshot. If it did update it may have fixed your BLTouch issues as there was a known issue with it for a few days but if you are only trying this today it's unlikely platformio downloaded the old version.

Please supply your configuration files and hardware setup, including stepper drivers and temperature sensors.

@p3p Driver ES-D508 Y "closed-loop" X TMC 2208 no serie connect

I am not at all a beginner configuration.h and well configure the probes also there is really that with this card that I have problems all the others have no problem the card is new I have changed two times to be sure but still the same problems so no external problem just the marlin or update problems as you showed me

I am totally new to atom I did not know at all I always worked on IDE-Arduino so I do not understand yet libraries and atom updates

I'm french sorry for my english who is extremely bad sorry again and again

[gloomyandy]

To save you both some time, here is a previous post about this problem (see the following posts for some followup): https://github.com/MarlinFirmware/Marlin/issues/7076#issuecomment-431604801 @guanix it would still be very useful for you to post your configuration files.

[p3p]

Your stepper driver is not in general use so we do not have a default configuration for it, you need to set the values in configuration_adv.h to match the datasheet.

Looking at http://www.leadshine.com/UploadFile/Down/ES-D508d_V1.2.pdf (best guess on my behalf at your driver) it appears your driver needs extra long pulses compared to the usual divers (2.5us minimum), so you will need to set MINIMUM_STEPPER_PULSE to an appropriate value, remember 2.5us is the minimum so 3 or even 4 should guarantee you driver picks it up within a margin for error.

I assume whatever bus driver (logic level converter) you are using is suitable for the slew and frequency requirements.

[gauix4]

@p3p I did as I told you I'm not a beginner all is good let's see that I already did everything in configuration advance that I joined you above your comment ^^

[p3p]

According to your config you did not, your setup for A4988 (the default drivers), that work down to a few 100 nano second pulse width.

[gauix4]

@p3p normally everything is good

[p3p]

sometimes hardware runs outside of the spec "most of the time" doesn't mean anything. MINIMUM_STEPPER_PULSE should be at least 3 possibly 4.

[gauix4]

@p3p if I activate the bed auto leveling does not work anymore

[p3p]

I can't help from "it doesn't work" describe the situation or post build log if its a build problem.

[gauix4]

@p3p I stay with the update I tell you that in 20 minutes the time that everything starts on the road

[gauix4]

@p3p nothing has changed always shift in Y always the bltouch that does anything

[gauix4]

@p3p I feel that because I have large dimensions put small dimensions everything works properly 300X300X300

[gauix4]

@p3p a compilation problem nothing but still the same problems even with a delay add

[gloomyandy]

@guanix Have you used that driver successfully with any other board and/or firmware? If so which? Also have you used the level shifter that you built successfully with anything?

[gauix4]

@gloomyandy yes marlin 2xx no good marlin 1.xx ok MKS Gens 1.4 ok lerdge S ok lerde X ok mks robin ok

[gauix4]

that's why from the beginning I say it's 100% sure it's the marlin I never had any other worries before except the passage of Marlin 2

[p3p]

What was fixed by reducing the dimensions?

We are talking about a lot of separate issues here, which is a bit confusing with your short responses, this is for the missing step on your Y axis, you are now running Marlin on a much more powerful Controller, signals that used to be slow enough for your driver because it was as fast as the AVR could produce them could now be too fast. Have you read the datasheet and made sure all the settings are correct? such as MINIMUM_STEPPER_DIR_DELAY that defaults to 50ns.. the datasheet specifies this needs to a much larger value of 5000ns,

I'm not saying there is nothing wrong with Marlins LPC176x platform, but there a numerous people running Marlin on the MKS Sbase so it being a general issue is unlikely we are just trying to narrow the problem down for you.

[gauix4]

@p3p no problem I understand MKS robin,lerdeX, lerdgeS are boards 32bits I read the dates of my stepper there is no problem everything is well settled more I can program them

the manipulation that is going to fix all the problems was to decrease the lengths of my printer I had put 300X300 and everything was working properly

that I put the dimensions of my printer and that I print large parts much more works at least that's what I found I can perhaps be wrong

[gauix4]

I just reinstalled the gen 1.4 everything works properly... last week I used the smoothieware software everything worked...

[gloomyandy]

Are you running Marlin 2.0.x on the gen 1.4? If not perhaps you can try it. Does the BL touch work on the gen 1.4 with the full bed size defined?

Why are you trying to use Marlin rather then Smoothieware?

[gauix4]

@gloomyandy I'll have to try yes because I'm on MARLIN 1 and everything works perfectly because we can do nothing at all with smoothie firmware il me faut un auto bed leveling car mon imprimante est trop grosse impossible d'imprimer sans bed auto leveling smoothie has one but it is very poorly managed

[gauix4]

good marlin 1 on the gen 1.4 it does not work either it shifts Y but I've already tried it marchai good marlin 1 on the gen 1. ' it does not work either it shifts Y but I've already tried it walked I do not understand anymore

[gauix4]

test that it does not work either check my signal 0/5 volts ok I use booster at the https://fr.aliexpress.com/item/LERDGE-3D-Printer-Board-Adapter-Module-External-High-Power-Switching-Module-for-Microstep-Driver-with-3D/32821023876.html

[gauix4]

person to an idea ?

[p3p]

Sorry Simon at this point without the hardware to debug with, or anyway to reproduce the problems you are having, it's difficult to help.

That stepper configuration should have more than sufficient delays for your Y stepper driver, the problem with levelling at large dimensions worries me but I have no way to test that and it's not really my area, you may have better luck with UBL rather than bilinear.

The temperature fluctuations shouldn't be possible without huge amounts of noise as there is a lot of software filtering, but that at least I can test.

[gauix4]

@p3p I can still try anyway I am open to all at this stage I do not know what to do other than change its driver and engine I never liked them

[gauix4]

@p3p we can see that the shift is not random

[gauix4]

@p3p this is on the last 1xx Marlin it does the same thing on the 2xx marlin last time i tried with a former sailor one that worked fine so i think there is an update made that generates this problem when do you think?

[gloomyandy]

If you think that is the case, work your way back through versions to see if you can pinpoint which change is causing the problem. Have you made any changes to your configuration since you had a working system? What about the hardware any changes to that? Are you using the same speeds wtc. as before?

[gauix4]

it works according to the parts there are parts it prints across there are non parts

[gauix4]

and therefore order real brushless motor (clearPath ref: CPM-SDSK-2310S-EQN) even though I think the problem will still be there at least I will have a good brushless motor with all that goes well

[gauix4]

@p3p I received my new clearPath engine and nothing function so I started my research and I realized that the problem was coming from ENABLE the signal is not clear at all when I plug on 3.3V everything works

Hi everyone,

I am a student in Turkey and ı also see like that problem. My drivers are also leadshine es-d508 and es-d808. I couldn't solve this problem. Are there anyone to solve this problem ?

actually ı solved, but my speed really low which is 20-25 mm/s. And surface quality is really bad in like sphere parts. I increased the pulses/resolution to the 5000. Thats mean, 4 mm pitch / 5000 pulse = 0.0008 mm. But surface quality in sphere parts and velocity are really bad.

3D printer is mu capstone project. ı must solve this...
