What do you really get for a $350 desk top engraver ?

well i was wrong and it turned out to be a control signal setting on the driver with a dip switch. things move under power now.

i would love to see what this could do with a better computer? the computer seems to be the weak link. i think i still have room for finer tuning, cutting back on the micro stepping helped a lot with acceleration. but the X and Z axis seem to work well. the tandem Y i have not figured out how to test with no home switches yet?

today was a good day

You can test Y tandem axis by using immediate homing till you get the sensors set up:

i have a bunch of mechanical mico switches and double shielded cable with all wire connectors needed for that i just need to order some M3 screws so i can mount them. plus i need to do something with cable management and do have some drag chain on hand as well. the one thing i did not care for with the motor and driver kits i got was how bulky the cable ends are. the aviation connectors are not bad the encoder connection is a different story. the shield grounding on the factory encoder cables is not the greatest since i think it is a pigtail of some sort? i hooked them up regardless. one other issue with the kits is the cables are pretty short so by the time you run it you don't have much to work with at the enclosure end. i might have to get some connectors for there so i have some extra wiggle room.

as for the VFD i have a separate enclosure to isolate any EMI that comes from it. double shield cable pretty much everywhere there. the rest of the system is just some commonsense layout keeping power wires away from signal wires and from what i have seen out there anything below 50V DC (I'M RUNNING AT 36V) is not to much of an issue with EMI but i avoided running signal wire near those as well.

i have a problem with my tandem Y axis but i know what the problem is i just don't know how to fix it my motors are going in different directions meaning one has to spin the opposite direction in order to move in the same direction as the other because of how the machine is built Tommy i figured you would have seen this one a mile away since you are the master of belt drives

i'm thinking you can just invert something in the software but could use a little help to get pointed in the right direction so i can fumble my way through this over here

Change the STEP_SCALE to negative on one drive in your ini file
