That's terrifyingly large, but I think I can print it if I do it sideways. Whoo! I'll be printing ASAP then!

Your firmware controls the *max* rates things can happen. You slicing program controls the rate at which things print. It sounds / looks like you have a very slow set of speeds set in Slic3r (or what...

Thanks, for the info, I tried some higher speeds in the Slicr and noticed some improvement. But when I use manual controls the Z-axis moves fine, I get the slow, noisy moves in the X/Y directions....

@Guizmo: You only need a split between the two sides if you are going to use the same arm blank for both sides. The gears are off by 1/2 a tooth from side to side but there is a 10mm gap.

If you are running the normal controllers, a Vref in that range may put less than 1/4A through the motor windings. What sort of current are your motors rated for? We get away with less torque than the...
View ArticleRe: Delta-Pi Endstop Problem in Repeteir
The motors are rated for 1.2A at 57oz of torque. Do you think the delta configuration is requiring more torque than the Cartesian setup? I tried vrefs at .4 or .5 volts but that seemed to make the...
