Hello everybody !
So, finallty the CNC is done and we run the first test of cutting… And here is the problem !! We tried a lot of different parameters and dxf, but the same bug happen radomly during the cutting… !
In fact, the CNC follow the repetier and also the cut we want to do, but randomly, it become crazy and unfollow the code to make is own way !
Because pictures are better than poor explanations, here are some results of this :
Please guys help usssssssssss !!!!!
Thank you !!

Your feed rate is way too high. I’ve been engraving at 90 to 100 mm/s, you’re trying to cut at 2,502mm/s.July 28, 2016 at 4:08 am #15343
Hello Barry ! Thank you for your feedback ! So you think it’s my feed rate who can change also the direction of cutting ? Because first that cut very well but quite randomly, the way of the cutting change completly and don’t respect what estlcam and repetier ask to do !
So to change my feedrate, i change it in estlcam ?
Do you think feed rate impact the global shape of cutting also ??
Thank you !July 28, 2016 at 5:13 am #15350
If the feedrate is too fast, you can miss steps and get bizarre results. And they will not make sense in a similar fashion to what you see there.
I set up the feedrate in estlcam for each of the tools, and usually set up one or more tools for each type of cutting I will do.
I think a huge feedrate can cause very strange issues in the cutting shape… Though my experience there is more from my laser cnc than the mpcnc.July 28, 2016 at 5:25 am #15351
Ok thank you for the feedback. So th feedrate must be changed ! I change it in the tool directly in estlcam ?
Wich feedrate for cutting laminated wood 5 mm do you think it’s the best ??July 28, 2016 at 10:43 am #15368
Have a look at the intermediate walkthough for an idea about speed and depth for a 1/8″ bit.July 28, 2016 at 10:44 am #15369
