Web Goblin cnc has begun

ITS ALIVE and moving!

I have finished the wiring and connected up the drives and limits.


The panel is a bit crowded but its what I had around and I didnt really want to spend £100 on a new one.
Those drivers generate quite a bit of heat so looks like I will have to install a couple of cooling fans.
I had a bit of a problem getting the pc to talk to the CPU4 control card but this was down to the pc and is sorted now. I have roughly set up the limits and Homed the machine in manual and can jog it around now. One problem I did find was when I tried to home all axes at once the machine homed X,Y and Z ok then tried to go find the A axis which is currently set to Slave X axis. I think I need to edit the Home all macro to fix this though. ( might have to pick Adcnc's brains a bit more)
The Y axis drive belt is sliding off the pulley as well so it needs a bit of fine tuning.

Looks nice and tidy to me. I don't think you should connect the mains wires to the drivers one after the other. This will cause each subsequent driver to get a lower, and varying, voltage to the previous ones in the chain. It's better to have wires from the live and neutral all connected to the same point, then connect that point to the mains. It may well not make a difference, I'm not sure!

I had a similar problem when setting up Chip's router. I didn't need to edit the macro. If I recall correctly the problem was with the breakout board - it failed to read the inputs if more than a couple of switches were active. That really messes things up when Mach3 tries to home both the X and slaved axis quickly.

Jonathan's right, in that ideally you shouldn't daisy chain the power wires, but I'd say interference/poor connections are a bigger hazard than lower voltages.
