Bed coming closer when doing probe_calibrate
Hey everyone,
I'm currently at my wits end. When ever I do a probe_calibrate I see the Z getting smaller and smaller. I'm uncertain what the problem could be. At first I thought it was my motors or a connection / screw somewhere that was loose but I checked that. I dont think it is binding because the bed is "overshooting" its target, because it is moving closer to the nozzle not further away. I'll design and print a dial gauge holder and clamp that to the X Extrusion and move the bed manually when I get the chance this weekend to see if its my motion system or the probe. Maybe one of you has another tip in the mean time what I should or could check.
I am using a 3DTouch probe on a 500by500 V-Core3.0 Probe was used on 250,250.
Here are three results done one after the other:
-> probe_accuracy probe_speed=2 samples=50 sample_retract_dist=5
First: probe accuracy results: maximum 1.191562, minimum 1.143437, range 0.048125, average 1.166825, median 1.166094, standard deviation 0.012841
Second: probe accuracy results: maximum 1.147500, minimum 1.102500, range 0.045000, average 1.123575, median 1.123906, standard deviation 0.013060
Third: probe accuracy results: maximum 1.100625, minimum 1.048437, range 0.052188, average 1.076475, median 1.076875, standard deviation 0.013948
Here is my BLTouch Config:
BL Touch
[include homing/bltouch.cfg]
[bltouch]
sensor_pin: ^bltouch_sensor_pin
control_pin: bltouch_control_pin
speed: 5
pin_move_time: 0.675
sample_retract_dist: 10
probe_with_touch_mode: True
stow_on_each_sample: False
pin_up_reports_not_triggered: True
pin_up_touch_mode_reports_triggered: True
x_offset: -28
y_offset: -13
Thank you for reading my post 🙂

Z-Axis wanders when moving
Hi all,
after printing alot on and of with my VCore3 500 I've run into my first major issue.
When doing the bed tilt my machine often times out. The second Stepper (front left when viewed from behind) is always at aroung 1.12-5 when the 3D Touch probe triggers but the other two are closer to 1.19-23. After checking the mounting for the anti backlash nut block I ran the probe accuracy test on all 3 probing points and saw that my Bed drifts down ever so slightly. Next I noticed that my front left corner (when viewed from behind) is always a little too far from the buildplate and the lines dont stick well. Even when using an adaptive Mesh with 10x10 Point for a print thats about 10by10cm. After that I moddled a quick holder for a dial gauge and ran a test with it moving Z to 10mm, then 1mm and back to 10. Over the course of 10 cycles my Z Axis drifted by 0.05mm. This sound bad when doing alot of z-hops.
My questions now are:
1. Is this normal Behaviour?
2. Am I chasing too much acuracy?
3. If it is a problem, where do I start troubleshooting from here?
Thank you all for reading this wall of text 😄

Manta M8P + CB1 Stepper Error
Hey all,
I'm currently trying to set up a V-Core 3 500 with an M8P&CB1 Combo. Klipper is installed and so far heating, fans and Endstops work.
When I try to home my printer I receive this error: TMC 'stepper_z' reports error: GSTAT: 00000002 drv_err=1(ErrorShutdown!)
I've checked the wiring for an octopus Board (A1,A2,B2,B1) and changed it for the manta (B2,A2,A1,B1) according to the wiring Diagram (black,green,red,blue). I also checked the connectors for shorts. Lastly I cobbled together the whole printer.cfg from the RatOS-configuration GitHub. I tripple checked the pins for my Manta and replaced all the aliases correctly.
Can anyone point me in a right direction or even better offer a solution?
Is there anything else I need to provide for help?
Thank you for reading!
