Welcome to the SeeMeCNC Community

Final update...I guess I'll call it resolved. By some miracle, it seems like my bed leveling, assembling and disassembling the hotend, recalibrating everything, and everything else I tried has finally fixed my issue. I'm sad to say I'm not sure exactly what it was, but so far I've got another 24hrs ...

I wasn't off too much, but now it's level within 1/1000 at each tower and in the center. If I bisect the towers along the same circle it's a slightly different story. within 1/1000 between Z and Y towers, but about 5/1000 high between z/x and x/y. What gives? Is it some weird geometrical issue or am ...

Dial indicator attached. With center as zero and moving 100mm from center, I'm reading 10 thousandths high in the +y axis, 10 thousandths low in the -y axis, 2 thousandths high on the -X axis, 10 thousandths low on the +X axis, and near the towers it gets wonky. I'm going to go back through the ...

Aha! Didn't see that. Nevertheless, I adjusted my stepper current and still no joy. Stairstepping like mad. I'm wondering if I'm looking in the wrong place here. I actually saw it do it for once today and it looked like the hotend got caught on the print and missed steps that way. Could that be the ...

Cheapskates have been adjusted and re-adjusted. Still did it in the middle of a 6hr print today. I think it definitely must be something binding or stepper current being incorrect; the motors run very warm to hot (Poor man's thermometer says ballpark 160-170F) and I have no idea what the proper ...

Update: My girlfriend called SeemeCNC while I was at work and explained the issue to them. They recommended checking tightness of eccentric spacers on the cheapskates. Basically, if you can hold the bearings/wheels still with your fingers while you move the carriage up and down, it's too loose. She ...

I'll check it out in the morning. Just confirmed it definitely still does it, it's moving left along the X-axis.

I've completed a few prints with no problems. It seems to happen semi-randomly. I'll update if I have it happen (I'm sure I will).

The belts and pulleys all check out OK. Could this be caused by belts being too tight? They seem about the same, or just a little bit tighter than the ones on my Prusa i3 and my Overlord Pro.

Yeah, they came with mine. They do have a flat and I used loctite, but its worth a check anyway.

They're neither- They're all black motors instead of black and silver, and are labeled "Automation Technology Inc", not kysan or wantai.

Edit: They're these ones: http://www.automationtechnologiesinc.co ... 3d-printer

Hey all, I've had my rostock for about a month, and it started out pretty awesome. Lately though, I've had problems with it turning my prints into staircases. My belts are tight, stepper power is set to recommended values, and nothing is binding. It seems to happen randomly, and it hasn't always ...
