How to wire BLTOUCH to anycubic 4 max pro?

[Erik262]

You can use this...

@Erik262 Hi, is this your printer setup? If it is, can you show me how you put the BLTouch sensor on the hot end? And please tell me the pin of where to plug the bltouch sensor? Thanks.

I put my BLTouch sensor inside of the head case. The wiring is exactly the same as the "I3Mega". Take a closer look on the picture, my connectors are labeled like this one: Cable Color (GRB) where is 'G = +' and 'R = -' etc.

Hi, just wondering as it says everytime I compile the Marlin, the current marlin onfile is old and need to be updated. Could you help me how to solve this?

[Erik262]

There should be a precompiled version available here. If I'm correct.

[kennethgomez01]

even your precompiled is causing error.

Try this from my repo: https://github.com/Erik262/Marlin-A4MaxPro-2.0.x/tree/bltouch

also why the probe is not extending when I press autoleveling?

Did you set G29 in your start script? Here is an example of mine. But be careful, my settings might not work without any issues. So keep this as an example.

G21 ; set units to millimeters G90 ; absolute positioning G1 F3600 ; set standard speed M107 ; turn all fans off G28 X Y ; home X and Y axis G28 Z ; home Z axis M140 S{material_bed_temperature} ; set bed temperature M190 S{material_bed_temperature} ; wait for bed temperature G29 ;autolevel M500 ;save data M420 S1 ;retrieve mesh M300 S1108 P105 ;play melody M300 S1661 P210 ; play melody G1 X-5 Y5.0 G1 Z0 M104 S{material_print_temperature} ; set hotend temperature M109 S{material_print_temperature} ; wait for hotend temperature G92 E0.0 ; reset extruder distance position G1 X-5 Y40.0 ; wipe nozzle on brass brush G1 X-5 Y5.0 ; wipe nozzle on brass brush G1 X-5 Y40.0 ; wipe nozzle on brass brush G1 X-5 Y5.0 ; wipe nozzle on brass brush G1 X0.0 Y5.0 Z0.25 ; set starting point G1 Y60.0 E4.5 F1000.0 ; print intro line G1 Y100.0 E21.5 F1000.0 ; print intro line G92 E0.0 ; reset extruder distance position

@Erik262 Hi I am just wondering as I am having toruble with z-offser(value is negative) for few days, just want to know is there z offset wizzard for anycbic 4 max pro?

[Erik262]

As far as I know, there is no z-offest wizard in that Marlin version.

[kennethgomez01]

@Erik262 just question did you remove the z-max switch for bltouch? Because I followed every totorial about z-offset but not be able to succed. I am getting bed not sticking

[Erik262]

No, I did not, but if it is touching before the BLTouch does, you have to move it up a bit. You might not save it correctly in your EEPROM or something else. Try to set the z-offset manually by using a feeler gauge (no paper!) and the wheelknobs under your heatbed. Then do your BLTouch stuff.

[kennethgomez01]

@Erik262 can you take a pciture of your setup of bltouch attach to the extruder?

[Erik262]

@kennethgomez01 Here are some pictures of my setup on Thingiverse: https://www.thingiverse.com/thing:4090425

[kennethgomez01]

@Erik262 are you using the clone? Why I keep getting print not sticking in the bed in some area of the bed? Can you share me the slicer setting you use, and grid points?

[Erik262]

I used to use a clone. Now I'm using the original one. The reason why your prints are not sticking on the bed is probably that your z-offset is not correct or you have some weird concave areas on your printbed. You might have to make a fine grid. I think I set in the settings to 25 points. I'm not sure. Or use a gluestick :)

[kennethgomez01]

@Erik262 how do you manage to set z_offset? Mine I change the hot end to v6 but the heatsink is same.

[Erik262]

You have to set up your z-offset only once like you wouldn't have a BLTouch. Then correct your z-offset with your BLTouch. If you have the wrong z-off set, you will provide this at any place on your printbed. You can change your offset by using the code M-851 or something else. This should be the easiest part. It's been a few years ago since I set this on my printer. I don't know everything what I did there.

Thanks @Erik262
