4 xxl cutting to deep

I was cutting out some letters and numbers (scrabble letters) using 5x5 tiles. did the first set and it turned out great. started the second set (reset z zero) and now it is cutting about a 1/4 inch deep, although I have depth set at 0.0250, I deleted the gcode and redid the CAD and toolpaths and ran again and the same thing is happening

Using a 90 degree vcarve bit if that would matter??

Is the machine mechanically sound?

Is all the wiring in good condition?

Let us know at support@carbide3d.com and we’ll do our best to assist.

sounds fine. rapid positions/jogs great. the machine is less than 1 month old and has worked well until last night and today after switching it cuts the number out like it is supposed to, it is just significantly larger /deeper than it is supposed to be

Here are some pictures.

this is supposed to be 0.005 inch

this is the one from the night before done at 0.025

You mention rezero the z. How did you go about doing this?

jogged to the front of the machine, then to the bottom left of the material, moved the z axis down until I couldn’t move a piece of paper. clicked set zero, zero all, done.

Okay. I was thinking it could have been a bit zero type problem as i have placed it wrong during the process when i first started.

If your still at the machine can you verify the zero is set where you had it still?

how would I verify it?

Jog back over to where you set zero and lower the z slowly because if your plunging that deep it could be set low for some reason. Watch the z height on carbide motion until it goes to all zeros.

Please see:

all ZERO’s… not sure what I am doing wrong…or how it went wrong from last night

Here is the .nc file if that helps

You did not mention if you have a BitSetter on that machine (or maybe I missed it), in case you do it could be a subtle workflow issue, see:

Hey i recently bought (about 3 weeks ago)a 4xxl after about 2 weeks it would randomly bore through the material in the middle of a project or move around without lifting etc etc aftera couple if dats of going back and forth with tech support they sent me a file to run and i had the same problem of it not following heights or paths correctly …carbide sent me a new controller its been used now for a few projects with no hiccups so lets knock on wood that it doesnt happen again after 2 weeks…also i noticed the new controller doesnt stop or momentarily pause when jogging like my previous controller did
