RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
It's a fully custom printer I've been tinkering with 2+ years; Core X/Y with a single Z axis drive and a 20x20 cube chassis.
The thermistor is the standard thermistor included with the E3D V6 Lite. The bed thermistor is outlined in the above comments. -
RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
@Phaedrux
I believe @Veti was indicating the default thermistor my bed uses based off the reprap auto configuration tool is wrong. I wasn't planning on using the PINDA thermistor as I only ever print with the bed at 60c and plan to do the mesh grid probing at that temp so there shouldn't be variance, correct?
Reading up on the PINDA temp compensation was rather perplexing TBH. -

Thank you very much @Phaedrux for the assistance; I got all turned about when messing with the offset/axis limit/homing commands and your assistance was quite helpful (as well as all others who chimed in)! -

RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
@Phaedrux Apologies, I'm quite shite at explaining the situation...
It is a Core X/Y, and positive should move the bed down away from the gantry I believe (jogging positive results in the bed descending).Here's the process resulting in failure:
- Home X + Y
- Home Z (with updated homing code provided above)
- Send gantry to x150, y150
- Send gantry to z0
- Observe nozzle is still ~4mm away from print bed
- Observe this distance is right where the PINDA sensor triggers
- Cannot raise bed (send negative movement commands) without disabling axis endstops (M564 S0)

RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
@Veti Currently have the following 24v bed with integrated thermistor; according to the comments it has a NTC 100k 3950B thermistor.

RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
alright, I've updated the z-probe offset information, updated the homeall.g/homez.g file, ran through the z-probe calibration process outlined on the above link, and updated the config.g file; still after homing, the z-axis raises the bed only to the trigger height of the sensor; it refuses to go negative past the trigger height.

RE: Unable to set Z offset with PINDA probeposted in Tuning and tweaking
Alright, I updated the G10/G31 commands as instructed and still cannot get the printer to jog negatively past 0mm.
Here's my updated config.g.
As for the thermistor config, that is what the reprap auto config tool gave me; if it's wrong, I am unsure what to update. -
Unable to set Z offset with PINDA probeposted in Tuning and tweaking
Hello all,
Installed a PINDA probe and I'm experiencing major issues with setting the z-offset; I set the offset withG10 P0 X0 Y0 Z4and after probing the z-axis I see that it reports the z-axis as positive 4mm when I tell it to go to 0mm withG1 Z0. When I attempt to jog up past 4mm it does nothing; jogging with any settings results in the printer refusing to go past the point the probe reported as 0mm...
I've removed the z-axis minima value from my config.g file, and I'm at a loss for figuring out how to get this to work.
Please see my config.g and homez.g. -
RE: Core XY Motor Movement Debacleposted in Tuning and tweaking
@engikeneer I was running a G91 for relative move followed by a G1 H2 X5 F2000 to move along the x-axis; it seems this series of commands side-steps the Core XY calculations and resulted in the issue I was experiencing.
I have run the homing sequences on my x and y axes now and everything is working again; the reason I was not doing this is I wished to ensure the axes moved in the proper direction before attempting the homing sequence (I use motor-stall homing on all axes).
Thank you very much for the suggestion, I am unsure if the experienced issue is a bug or just the expected outcome; either way your help is much appreciated!! -
Core XY Motor Movement Debacleposted in Tuning and tweaking
Hello all, odd one here.
I recently revamped a Core XY based printer I've been building for the last few months and essentially rotated my belt design 180 deg; after completing the physical change, I connected my Duet 2 Wifi back up and inverted the X/Y drive settings. Now when I try to move the shuttle along the x-axis it rotates only the motor connected to the x-drive port on the Duet.
I've tried the following with no luck:- I've reset my firmware to factory and then manually added the M669 command for Core XY
- Used the RRF config tool to generate new firmware
- Tried all 4x combos on X/Y motor directions
- Run M669 command in console followed by G91/G1 commands to try and move axis
- Ran M503 to list settings and verified printer is in Core XY mode
I am seeing the same issue along the y-axis too; only the motor connected to the Duet's y-motor pinout is rotating.
At this point the only explanation I have is the printer is stuck in standard X/Y single-axis movement and cannot run in Core-XY mode, but I'm at a loss for how I can force it to reset/undo this.
Thanks In advance for any assistance!
