Having issues with speed on homebrew machine.

[Dingo420]

i have played with this for 9 hours now and cant get the speed to increase. i can drop motor max speed, to about 200 and notice slight decrease from allready slow. i try 400, 800, 1000, 1200,1500,3000,50000,80000 and cant seam to affect speed. checked and changed stepping info, recompiled with different settings. it draws slow but will home fast...... any ideas?
seams to be waiting on BUSY: C17 ,###,###,#,END

it does about 1 line of code a seccond...

If you're using C17 to draw lots of small lines then the motor never gets the chance to run fast - any motor speed is interrupted by the continuous call-and-response from the communication protocol.

The default "shortest vector" setting is 2, so that means that curves are chopped into lines no longer shorter than 2 motor steps, so that is usually lots and lots of very tiny lines. You can adjust the "shortest vector" setting so that the lines are longer, but the fidelity of the drawing will suffer, and you may find it won't speed things up much anyway.

The only way to run complex vectors quickly are to build a machine with an SD card, and run the commands from the card.
