The one i have is 2 x 25v so i was expecting more like 70v, and the drives are the 2DM860H so can handle the voltage ok

You might find the transformer has a primary rated at 220 or 230VAC and your stuffing 240 up it, with the proportionally higher secondary voltage. Under load you're going to see a reduction in terminal voltage anyway - so long as the electronics can take the peak voltage okay then I wouldn't lose any sleep on the 75V output. I have a 600W 50V toroidal that also gives me an unloaded 75VDC on the caps, and I chose the same drivers for that reason.

You are right Clive, that was tested with no load. The drives do take upto 110v DC and upto 80AC. I didnt think about connecting the toroidal direct to the drives! Im assuming they have their own rectifiers and caps to smooth the currrent then? But i also assume the same 75v would be achieved?
I'm thinking i might test it again in the evening when demand for electricity is higher...i measured it at about 4pm on easter sunday when everyone else was probably out having a bbq!Last edited by CharlieRam; 22-04-2019 at 09:02 AM.

Well I've been busy doing the electronics and control cabinet and familiarizing myself with the AXBB motion controller, its my first one so can't compare with any others but i must say I'm impressed with it. I have completed almost all of the electronics but before I fit the motors to the machine I want to make sure the limits are fitted just in case! Is 5mm from a hard limit a good distance or do i need more? I think I may of gone a bit overkill with the cable chain too!
