I’m having an issue with my Taz 6 during leveling. It will level just fine for the first two washers; however, when it reaches the third washer, it doesn’t move far back enough for the nozzle to touch the washer. Instead, it digs into the edge of the bed, causing it to bend slightly and lead to a failed bed leveling. I’ve leveled out the x-axis and it moves far enough to the right where it would touch the washer if the bed had moved further forward. This leads me to think it has something to do with the y-axis not moving far enough, but I’m not really sure what the problem is.
Ensure that your Cura LE printer is set to be using the correct toolhead. If you are not 100% sure what toolhead you have (not uncommon to mistake a SE for a Single Extruder, for example), take a picture of it and post a reply.
Plug the printer into your computer’s USB and update the printer’s firmware for the correct printer/toolhead combination via Cura LE.
In the printer’s menu with the latest firmware, it should have a toolhead menu. Select your toolhead.
Try printing again with a freshly-sliced file. If this fails, posting a video of what’s happening will help the most.
Possible mechanical reasons are something is physically blocking movement, or your print bed is not in the correct spot and has shifted, or a loose belt.
Possible software reasons could be that your steps/mm got changed.
Hardware failures could be a failing stepper or driver.
I have a Titan Aero Pro X purchased in 2021 running on a Taz6 (legacy). In going to the 2.0 firmware with CuraLE from 1.1.9.34, what do I specify for the tool head? I used Taz Aerostruder with the 1.1.9 firmware but bed level results are poor choosing that for the 2.0 version.
There’s some old printheads that are an exception, but all modern official toolheads (including unofficial ones made by itworks-3d) share the same x/y offset, so select your toolhead based on your nozzle in both Cura and through the toolhead menu on your printer: SE 0.5 for the standard nozzle, HE for a hardened nozzle, etc.
Thank you for the reply. I tried that selection on the Toolhead menu displayed on the LCD. In Cura LE I am using the TAZ 6 Aerostruder for the printer. Choosing the HE 0.5 on the TAZ6 (tried SE0.5 as well), I still get the probing shifted so that it is too far -X and +Y (ie just hits the edge of the right front/back washers). There is a setting in Cura for the location of the first probe point as a G1 command. I tried that with no effect. Is it overridden on TAZ6 even though I evaluated the setting by exporting the G-Code from Cura and run it via card on the TAZ 6? I did enable the M209 command line to shift the wiping to the left by 2mm. That did work so the machine settings seem to work. Thoughts?
That G1 is just a move command to get it close to the washer at a standard feedrate. The G29 leveling command is hard-coded in the firmware with locations to probe.
The probe locations are affected by the adjustments in the M209 command, so they can be used to fine-tune the initial probe location.
