Tip of the dual extruder scratches the model during travel

Snapmaker Artisan
1

Hello everyone.

I have an Artisan with the dual extruder for a few days now. The two rulers for X and Y calibration always looked a bit unsightly, but they did their job. The first prints of parts were of good quality. In the left hot end was the orange PLA that was supplied with the Artisan and in the right one was the white PLA support that was supplied also. I’ve never needed the support so far, I’ve only printed with orange.

Now I have replaced the white PLA support from the left hot end with normal black PLA so that I can print orange and black at the same time or one after the other without having to change over.

This worked well for half a part - then I had to pause the job because I had an appointment and didn’t want to leave the machine unattended. I pressed pause, then the emergency stop button and then turned the machine off and unplugged it. I had read somewhere that you can continue the job after switching the power back on. When I switched the device back on I was able to continue the job, but it didn’t work well, the layers didn’t stick.

Since then, I have the problem that the tips always scrape over the already printed ones. To me it sounds like a problem with the Z calibration but unfortunately after calibrating the whole machine several times I can’t get rid of the problem. Does anyone have any ideas?

I would normally suggest increasing Z-hop, but Luban doesn’t appear to have that option. Big omission IMO.

There is a setting for “Avoid printed parts while traveling” that might help.

Not sure if your process is the right approach. Once the power goes off, the machine didn’t move in any direction and should restore the job once the power is back.

But you hit the pause button and afterwards the emergency button. We would need to know what the device is doing after the pause button was pressed. Maybe writes some code in the print job to start a little lower to avoid gaps?

Just thinking, not knowing…
