I have a delta printer. The problem is that after the start gcode is executed and the extruder head is 15 (Pic: x0) mm above the center of the plate, the first move towards the start (x1) of the actual print is performed at (maximum possible?) speed @ infinite acceleration. After that the print is performed with regular acceleration. This can cause missing steps.

The problem seems to arise after the start gcode section. How can I fix it. I use Cura 3.5.

By way of comparison, here's what Cura writes as the header of a gcode file. You may want to adjust some of the default parameters in your Cura settings. (this header was same for both the default Prusa and the default Deltabot printer settings)
