Repetier-Host loses track of X and Y axis values after M114 D gcode.

softfoot

I am running v2.2.4 of RH under Windows 7 x64 Pro with 8Gb of memory.

The printer is a Geetech i3 Pro C running Marlin v2.0.9-3 firmware.

If I click the Home All Axies button on RH then issue the "M114 D" gcode command it causes RH to clear the X & Y axies to 0 - they SHOULD be the same as after the Home.

The firmware still has the correct X and Y values but the zero values cause erroneous manual moves generated by RH.

M114 D is a debug command used to examine the firmware bed leveling parameters and doesnt change any settings or statii.

NB This happens under v2.2.4 of RH - it also happens under earlier versions (eg 2.2.2)

Can you please provide a response from M114 D to log? I have seen variants e.g. with 2 lines bus same markers X: Y: on some firmwares, so need to know the special case to verify it against our parser solution.

I hope this helps

Makes sense - we search for X: and we then use the last line. Have see it in same line after "Count:" as in first line with -D but not such a mess. Need to add exceptions ignoring all the worts at start. Also wonder why there is no "echo:" as marlin adds it to every line normally.
