I have it on 150mm/s, but the actual speed looks slower. My XY steps/mm are 319. I try now to lower it.

LarsK, Yes to all of your suggestions. I only tried shortly printing via USB and it started to do the same. I am printing G-codes. Yesterday I managed to get things better, but circular motions are still intermitted. Powersupply is the same but since the straight moves (diagonal or not) work fine, I would not suspect that to cause the intermitting in the circular moves. I have not been heating the hot end, infact it is off the printer. Te G-codes I have been dryrunning are set to be 0 temp. I noticed a huge gain in overall smoothness and speed after I dropped the steps/mm for the extruder. The extruder is also intermitting in the same phase as the motions of the gantry. I don't have an oscilloscope but I started to look for an used one yesterday. I try to upload a video of the problem somewhere, though I really hate how you can't nowadays do it without pain in the ass connections to Google or something else. The resolution issue has something to do with this, for sure. It's the overall counting for the electronics that has to be made lighter, I suppose. I just don't know what setting is wrong, or should I get some beefier controller for the machine because of the Corexy and the print size. Maybe they are a killer combo for normal consumer controllers? Can anyone name a controller able to do faster calculations? This has to be a fast machine, thats the point of it. I built it to handle serious speed and accelerations.
