Hi all

TL.DR: edm machine cutting slow! Settings?


Bit of a longshot as i couldnt find any EDM threads on here but thought id try.

I have a joemars AWTs machine and im currently cutting 100mm thick steel taking some cylinder blanks out. At the moment after using the S-code provided by the machine i keep getting wire breaks and ive had to lower my speed to 0.300 (the machine starts on 2.000 which is too fast) at this rate its taking the machine 6 hours to cut 145mm length of cut which just seems too slow, whilst getting a lot of wire breaks

Ive checked my contact pins there clean and roated, water is at 55k, water nozzles are close as i can get to the material.

Below you can see the settings (had to adjust to get the cut running) and then you can see the length of cut and time.

Thanks in advance!
