My x carve works good. It is able to move well on the X and Y axis. My issue is that the Z axis seems to be off. It can move up and down, but after I click CARVE it just keeps going down and it goes deeper.
I have it set on 0.075 for letter “A”, so it should not be that deep. Right? The machine would keep plunging until it goes through. I am struggling to understand how to fix that. Anyone experience this?
@AmberZion It sounds like you need to calibrate your z axis and change the setting in GRBL. Here is a video to show you how to do it. https://youtu.be/UHd9HgHDqMQ
Check to be sure you have the right settings and be sure you have selected the right acme screw when you set up your machine.
If you command a 1" jog up or down on Z, is the actual travel also 1"?
If one of the Z-stepper 4 wires have no/intermittent contact stepper will operate as normal but directional control is lost.
What do you mean? I checked all wires, and they looks good.
Where do you zero Z off of?
I followed the steps using probe.
Do you use the probe?
Do you use Easel as your design program or is it another?
It apparently that the shape works just fine, so I copied the same setting for text, but it is off. With text, it just carve deeper. Unlike the circle shape.
Look at the photos.
I have acme rod, and it works fine.
It looks like you are loosing Z-position, the most common culprits are:
- Check and double check your belt pulleys in Z, one or both may be slipping a little.
- Check your $112 and $122 values, they might be too aggressive, causing the Z to stall and loose steps during plunge/retract motion.
Have you checked them with a DVM for continuity?
If one of the four wires dont have contact with the stepper driver it may plunge instead of retract, and vice versa. This may cause your Z to drop as it carve.
