Then I tried without the graphic controller and miracle, all works fine.
Am I alone to meet that problem ? ( Marlin 1.03)
There have been at least a dozen posts here in the past 60 days warning people that the 16Mhz Arduino boards and a Full Graphics LCD max out the processor and memory when also doing Delta math. Repetier firmware's GLCD support is a bit more optimized, but still has stuttering problems at higher speeds. If you do not want to buy a 32-bit board, you can run your printer slower, remove the GLCD drivers, cut your steppers down to 1/8 micro-stepping, or reduce your number of segments as documented in many of the other threads on this topic.....
