I can try that. But before, i just saw that there are 4 tiny screws, which are responsible to hold the Z-Motor in position through that little piece of plastic - and when i checked it, i saw there is one completly missing and one is terribly loose. i tigthened the third one, but don’t have a replacement for the fourth tiny screw - will check on that later. But now i see, the Z-Axis is way more rigid than before. The router is held firm in its position, even if i apply some pressure on it above. (before it was able to go down with minimal force).
I suppose that was my Z-Axis problem - but i will confirm that later.
Yeah, i’m sure it’s firm. i can’t move the router in the mounting tool, and i cannot notice any wobbling in the bit.
I measured it with a caliper and no, not in the same place. the only way to have such differences is a warbed surface (of the work piece or work area). but i am pretty sure that’s not the problem. I really think the Z-Axis went down every inch a little bit.
Once i read you should go max. 50% DOC of your bit diameter. I guess that’s not correct? My cutting speed varies beteen 1200 - 1500 mm/min. What parameters would you suggest with a 3 mm bit?
Nice idea with the foam. I am going collect some of it!
I postet a picture in #20, you can see on one side i do have a nice perpendicular plane, but the other side has stairs.
not easy to check; i dont have a measuring tool for such short distances. i need to think of another solution.
No i don’t think it’s wobbling. router and bit are held firm and securely.
I am using the black GT2 belt; yesterday i noticed that the belt on one axis is damaged: if i move the axis over the damaged part, the machine starts to rattling and grinding. i need to replace it. Could this also result in my problems? I can upload a picture of that later. I tried to avoid the room where the belt is damaged without luck, but i dunno if the belt can cause troubles in a wider range?
that’s something i need to talk about. what is the right tension for the bearings especially on the trucks? i feel like i don’t get the rigth tension on them.
yeah i could live with some heigth errors. but in future, i might need a perfect depth in some occasions. so i would like to get a nice and decent working machine.
Thank you very much for your help. I appreciate it a lot; i am going to work it out and post an update here with my knew knowledge.
Also, what about ambient temperature? My MPCNC is in a shed, not very hot in here. we had overnight like -10 °C and now it’s -4 °C. I can’t heat the shed in a sufficient way, but temperature should be above 0 °C. This is my first winter with the MPCNC, and i am wondering how the temperature will affect the machine especially the plastic stuff on the bearings?
