Unable to read tmc uart 'stepper_z' register IFCNT
Hello, i have the vcore 3.0 500
steppers from ratrig
tmc 2209
btt skr pro 1.2...
Move out of range when performing Bed Mesh.
Running the new beacon rev H probe. tried adding position_min: -5.0 to [stepper_z] but no help. homing and beacon_calibrate working fine.
XY-gantry (to) rigid
I have a nicely built RR VCore3.1-300. It could run a bit better however. Let me explain:
If I mount the X-gantry to the Y-linear rails with the bolts slightly loose, the gantry (without the belts) runs super smooth to the front and the back.
If I then tram the gantry to the frame and I tighten the screws and/or the bolts (connecting the XY-joiners to the Y-linear rails, see pic one and two) it almost feels like the carriages of the linear rails start to bind up. It feels like the Y-rails are slightly under an angle (see third pic, highly exaugurated).
I did level out my whole printer and put a digital angle meter (protractor?) on it. I could find that the mounting plates have 0.1 degree variance to horizontal (this should not matter right? not taking into acount that a digital tool of 30 EUR can have this precision anyhow). I did try to correct this by loosening some frame bolts, rotating an tightening the 3030 extrusions again but this retightening brings back this same minor 0.1 degr. variation (on both the left and right side).

I am done
Hey, so I own v-core 3 (not 3.1) which I couldn't set up properly. It is 300³, skr-pro board with orbiter 1.5 and dragon HF. I cannot print more that 5 layers on it. According my small experiences first layer seems OK. But afterwards each layer it gets worse until the head bums the print away. I am using 0.4mm nozzle, set up completely new printer.cfg file, used external thermometer to prove the correct functionality of thermistor (PT1000), done pid tuning. Using superslicer with initial vcore profiles. Tried lowering and increasing temperatures, disabling fan. Nothing helped. I don't know what to do next. Thank for any helpful hand out there.
PS: Should the direct head ooze this much? Using E3DV6 nozzle. When I am extruding it seems there is microdelay between filament coming out and sending the command....
Perpendicularity of four upper profiles
Hello. I have been printing for about a year, happily. Today I found/was reminded during a maintenance and upgrading, of my geometry of four upper profiles. Two opposite corners are perpendicular and the other two are not. I am wondering, if anybody has had a similar situation and if fixing the frame by tightening it while some profiles do not touch has worked? See pictures for hopefully understanding the issue... It is greatly exaggerated but hopefully the geometry principle will be clear.
Bed mesh not flat at all
Hi, im just checking my frame alignment but I really don't know what to do with it.
I tried to rebolt all linear rail, but seems that X is a bit bent, or maybe I'm missing something.
Thanks in advance...
Loud buzzing sound coming from toolhead
I am encountering a very loud metallic buzz coming from my toolhead but cannot find the cause or solution.
It is happening during constant motion and not direction changes so not related to acceleration.
It does not appear to be a resonance issue in my opinion because it is the same frequency of sound coming from motion in both x and y direction and after changing the mass of the toolhead (switched from BLTouch to Klicky and even tested with partially disassembled toolhead).
Input shaping also has not corrected this problem.
