Hello again
so I tried this fix here: Wiper Comes Loose (White plastic ring on ball screw)
unfortunately it did not work.
I took out the white washers on both sides of the Y axle, cleaned them and put in some new oil for lubrication. At first I tightened the white washers a bit too much, which is why the homing on the Y axle no longer worked. So I opened everything up again, tightened the small grub screws just enough to hold the washers in place and allow the spindle rod to run without chopping or major resistance.
Then homed again and voilà, it worked great.
Then I fitted my milling cutter and started the milling programme again and … same problem. The cracking is extremely loud and it doesn’t sound good. On the surface, I can’t find anything loose on the machine.
To rule out the possibility that it was the milling cutter, I started the programme again without it and again the same problem.
Then I just moved the machine back and forth quickly with the joystick and there is absolutely no problem.
I made the milling programme and G code in Fusion 360 and have had no problems so far. Now that I have fitted a new wasteboard and want to drill, this is happening. Is it the code or the machine?
Here is a screenshot of my milling speeds:
