Problem with z-probe offset
-
Sorry to hijack this thread but would just like to get something off my chest.
Ive had problems with both my corexy printers regarding Z height and first layer issues since upgrading from RRF3.1.1. Both printers have SBC. They both now running on RRF3.2.2 and neither are capable of printing anything from scratch without my intervention. Each time I have to adjust babystepping to get the first layer height correct.
Example: In config.g one printer has Z offset G31 X-30 Y-5 Z2.72 which was found by doing correct process to find Z height. On attempting to print, Z is too high. If I lower Z by 0.28 using on the fly babystepping the first layer is spot on. Before next print I change G31 in config.g to G31 X-30 Y-5 Z3.0 so as to equal the difference with babystep. On next print Z is too low and babystepping back up by 0.28 corrects this!!!!
Just in case I'm doing something wrong I then change config to G31 X-30 Y-5 Z2.44 (minus 0.28). This time the print too low by 0.28!!!
Both printers have similar issue and neither printer has any other G31 command in any other piece of gcode or macro.
I have only one functional printer which is old faithful ender 3 pro which in my opinion prints every time because there's no Z probe present, everything is set up manually, no SBC attached and therefore much simpler.
Ever since RRF3 firmware versions have been available I've had issues and still have issues with SBC not always connecting to DCS, when booted up, sometimes config.g not been processed so DWC shows no extruders, no heaters, no fans etc...
It was months and months ago that i first reported an issue that any gcode command that I enter into the console in DWC has to be clicked on twice before DWC responds, I find that this issue is STILL present and has now even expanded to include the emergency stop icon on DWC. So at one point my head crashed into the bed because the emergency stop does not always work first time!!!
Lastly, I fail to understand how on both printers with SBC attached i often encounter "network failed, no network connection" showing on SBC's DWC but im somehow happily connected to DWC via laptop!!
I spent £1500 on my last printer but the best and most reliable prints come from my simple £250 Ender 3.

@chas2706 Im experiencing pretty much the same behavior . I need 0.280 in baby stepping to even get the print on the bed

@chas2706 Updated to 3.2.2 and removed a space i had before the Z numerical field in config.g and my problems have gone away
Good luck
