1 Day AgoIt should be in series with the motor. The fact it's been disconnected would indicate there's been a problem. Depending on how much money you're...18 replies | 738 view(s) -
2 Days AgoThat's a choke. They help smooth/suppress noise from the motor. It's worth checking it's not failed and gone open circuit (either with a...18 replies | 738 view(s)

3 Days AgoYou can connect a pot, which if you have one laying around (IIRC they're normally around 100k), I would wire up just to check the drive still works....18 replies | 738 view(s)

3 Days AgoThat's the early system. The spindle drive board (in your first picture post), should have everything marked on it. As it's a NEControl, I'm not...18 replies | 738 view(s)

4 Days AgoIn all honesty, without knowing anything about the machine, I'm guessing the DSC controller will be a proprietary controller and need specific...2 replies | 365 view(s)

4 Days AgoFor that one I linked to, typical turn on time is 0.1ms, and turn off 1ms. On a typical home brew machine, those times are going to be negligible...18 replies | 986 view(s)

5 Days AgoIt depends on what you're actually using the contactor for. If it's solely to control the main power, so you can use a smaller main switch, then it...8 replies | 862 view(s)

5 Days AgoMmmm...necrobump... But I did build a Voron last year, just because I wanted to have one. My Enders still do the majority of my printing though.8 replies | 14059 view(s)

6 Days AgoAs you've already got 24VDC, I'd use that to control any contactors, and have the 24VDC PSU hardwired (via a fuse) to your main power switch.8 replies | 862 view(s)

6 Days AgoNo, but from what I remember the main board had a processor built in, so there wasn't really much in the way of pinouts. Just motor/spindle...8 replies | 524 view(s)

6 Days AgoThat's a two speed motor which complicates things, but also means it's likely to only run on 380V. Dual voltage/dual speed motors are theoretically...8 replies | 524 view(s)

6 Days AgoIt all depends on if the motor can be changed between delta and star. Some motors are only labelled for a single voltage, but are changeable. It...8 replies | 524 view(s)

6 Days AgoProtective earths should never be switched. I'll also mention that in terms of control circuits, any operator controls should be low voltage (IIRC...8 replies | 862 view(s)

1 Week AgoThat complicates things somewhat. The diagram for the probe is just a basic functional diagram then, and there's a bit more going on in it. Have...18 replies | 986 view(s)

1 Week AgoIt depends on what output voltage the VFD is. Generally VFDs output a 3 phase version of whatever voltage you feed in, so if you want to run one...8 replies | 524 view(s)

1 Week AgoDid you manage to work out the wiring for the machine? Have you got any photos of what BOB (Breakout Board) is fitted? My suspicion is it's...17 replies | 1273 view(s)

1 Week AgoI did wonder what voltage the G540 pulled the input pin up to. In that case I think you'd get away with only connecting two wires to the probe,...18 replies | 986 view(s)
