Hi. I have a diy cnc with grbl i have set up every thing, calibrate the steps. I have now one problem, no meter what cutting depth i set it does not go more than 0.3 mm. I am setting the starting point above the wood with a paper. i am trying to make a clean hole about 19mm and when it finish it only 0.3 mm. can anyone help plz?
No is not a printer sorry for that. I have a 3D printer and maybe I got confuse because I have print all the parts for the CNC.
My machine is a diy with working area of 725mm on x, and 425mm on y, and about 70-90 on z. The movement is on 8mm threaded rode on x,y and for z 8mm rode with gt2 belt.
I am running grbl on arduino uno with cnc shild.
I have calibrated the steps. When I jog I can touch bottom but no mater what I set when I want to curve it does not go below 0,3mm and it drives me crazy. I do know the basics because I have a diy AM8 3D printer but this I can’t figure it out. I have attached a photo but is when I had the y axis 725mm working area now I have change and the x it the 725mm but you can see the machine and get the idea.
Yes very good i like it so much. No is not i have find it to thingiverse. Yes they are Nema17. I think is software side not mechanical because when i jog the mm are correct and i can go all the way down, if i had mechanical problem i think i will have discover it by now. As you see in the photo in Easel i have make the hole to go all the way down, when i start the processes it say approximate 1 min to finish isn’t that to quick for 10mm radius hole and 19mm depth?
I have fix it. I had to increase vref on steeper drive because it was too low and skipping steps, if i remember correcly is was 0,88 and i set it 1.05 and now i can cut the depth i set in Easel. tnx every one for the help.
