Lines in 3D Carvings Resolved

Lines in 3D Carvings Resolved

Postby zeeway » Thu Jan 09, 2014 12:30 pm

About six months ago, I started seeing a series of lines in my 3D carvings. Everything I tried failed, until I tightened up my rack and pinion drives. So if you have drives that look like this:

...suggest you loosen the motor bolts and pull that little belt tight...

....and the problem is resolved. I do not know if the belts stretch or the bolts loosen over time, but my suggestion is to do this every few months.

Hi Angie,

Thanks for the heads up....

I use those R&P drives and never really thought about the belts.

I'll have a look next time out to the shop !!

I have had a tensioner vibrate loose, so watch those as well.

Thanks

I'm blaming Angie for this! :lol:

Yesterday while routing, I think I thought I heard a clunk when the X Axis changed directions once in a while, but I wasn't sure, and the routed stuff coming off the machine looked great. Well, after I was done routing last night, with the steppers still powered up, I gave the gantry a couple nudges, and the far side had probably 1/8" of movement. I'll dig into it this morning, and hope it's just something loose, not something broken!

Wish me luck!

I forgot to ask... were your lines parallel to the direction of machining, or 90 degrees perpendicular to the machining direction?

Thanks!

Chris,

My lines were 90 degrees to the direction of the feed. (I didn't touch your machine, I promise :D ).

I have lines like that... or maybe like that since I don't know what yours' look like. I can mostly just see them and not really feel them, but I can feel a few.

Thanks!
