Driver goes unidirectional

[cropwell]

Well, I have taken delivery of three new drivers and wired them in this afternoon. I had a bit of a problem determining the microstepping of the old drivers, so I started from first principles and all seems OK, the machine is cutting properly to dimensions.

Ther is one small glitch to sort out, Estop and Limits seem to randomly trigger. They are NC circuits, so I need to consider what resistance there is between the GND on the BoB and the input wire to the BoB terminals. I'll do that tomorrow afternoon.

I am just pleased to have taken out those ruddy Tonman PD2064M drivers.

Cheers,

Rob

I sorted it, but it wasn't an easy one to spot. A wire had broken at a soldered terminal and the heat-shrink was holding it in place. When I put the cover on the box, the lid was pushing the 'joint' enough to disconnect it. With the lid off there was no fault to find with a meter.

Hopefully it is all 'solid' now.

Cheers,
