LarsK, It looks all cool. Straight G-commands make no problems. It's only with printing. Now I run Marlin. on 3Drag controller, SD all the time. Even when printing the straight lines (0 or 90deg) come nicely, but anything angled or diagonal will cause the freezing. Electronics run cool and the problem is identical every time. I have been swapping and crossing electronics and firmwares and even slby PropellerHat - CoreXY Machines
No. The problem appears as if it would be a error in the print file, but I just don't get why then the same file runs smoothly on my other printer. The weird behaviour is always the same, exactly same tiny pauses first and then in the same coordinates the slow motion.by PropellerHat - CoreXY Machines
I am finalizing a big volume CoreXY printer and now when trying to get it move right I find a weird problem with many different hardware combinations. The printer makes right moves but in a horribly weird speed. First seconds the printing looks nice (reasonable speed, a little bit of unwanted very short "pausing" on the way) and then the thing freezes almost completely - it barely moves.

Well I learned that the endstops are off on purpose when printing, so that's not an error even though I find that to be wrong, exactly because of stuff like my case. Othervise the problem remains unsolved.by PropellerHat - CoreXY Machines
Hi I just finished my CoreXY printer that I run with 3Drag controller and Marlin. I have tried some dry runs on it and both the files tried start to "print" nicely but after a minute or so the printer stalls for a second and soon after that everything goes wrong. The endstops are not working and the printer tries to push through them making the belts slip on the pulleys (thankfully instead of braby PropellerHat - CoreXY Machines
