Big Sized Printer Mesh Bed Leveling & Lead screw Adjustment

; Axis Limits
M208 X0 Y0:0 U0 Z0:0 V0 S1 ; Set axis minima
M208 X610 Y635:635 U635 Z950:950 V950 S0 ; Set axis maxima

You've used a mixture of old and new M208 syntax. Try changing this to either:

; Axis Limits
M208 X0 Y0 U0 Z0 V0 S1 ; Set axis minima
M208 X610 Y635 U635 Z950 V950 S0 ; Set axis maxima

or this:

M208 X0:610 Y0:635 U0:635 Z0:950 V0:950 ; Set axis minima and maxima

@dc42 : Thanks for the quick reply.

I have tired both, first one works with homing, but the mesh bed again goes to x0 y0 instead of X50 Y30. But the second one does not work for homing also because it may be missing a syntax (since it going on the opposite z direction).

Which firmware version are you using?

Pradeepkumar

2.0(RTOS) (2018-06-05b3)

OK, that's an old firmware version that doesn't support the new M208 syntax. Please upgrade to 2.02 or 2.03RC2.

Pradeepkumar

Does it affect the mesh bed leveling with G32, if so please send the link for updating the firmware, firmware with less bugs. Also if there a link on how to please share the same as well.

Here the link for 2.02: https://github.com/dc42/RepRapFirmware/releases/tag/2.02. Read the "Upgrade notes" sections in https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md for releases 2.02 and 2.02, to see if you need to change anything in your configuration files.

Pradeepkumar

I have upgraded to firmware 2.03RC2 (2019-05-14b2), But the mesh bed leveling is again going to X0 Y0. I think there might be other things to be changed. My issue is not with the minimum and maximum. The G30 P0 X50 Y30 H0 Z-99999 is going to X0 Y0 instead of X50 and Y30

Veti

it probes point X50 Y30

since that is your probe offset the position of the head is at X0 Y0 where it can probe X50 Y30.

Pradeepkumar

@veti Thanks for the comment, I did not know that G31 is for probe offest as well, I have changed, Now it works well. Thanks once again for help. Do you have suggestion for my comments below.

Is necessary to give the lead screw adjustment in the config file, but I have not declared. Because it is away from my print area
In homing all, when M584 P3 used, it does not work as expected. I have removed the same and it works well. Though I combining the Y axis the axis, but, I still see the extra u axis.

It's normal for the leadscrew coordinates that you specify in the M671 command to be outside the printable area.

The homeall.g file that you posted doesn't have the M584 P3 command. Where in that file did you try using it?

Pradeepkumar

@dc42 Hi I am using the M584 Y1:3; Joining the Y&Z axis, if i use M584 Y1:3 P3; Joining the Y&Z axis, is not joining the coordinates.
