Re: EMC2 Configuration for H1?
little confused on the A axis. I've converted the Z,Y & Z axes to inches, but do I do the same for the A axis? I know that if it was truly degrees, then it would not change, but you mentioned something about it not truly being degrees, but in mm of extrusion. So do I convert the 5 deg/rev like: ...

Re: Velleman Thermostat Not Working
narrowed the problem down to the relay on the thermostat not working properly. didn't want to wait to order another one so I grabbed one from radioshack, even though it didn't fit on the PCB. I simply screwed on an extension board to the thermostat, and ran wires from the extension to the proper loc...

Re: Velleman Thermostat Not Working
Possibly another clue. Just checked the resistance of the resistors. Together they are 3.6 ohm, which seems right, because that gives I = V/R = 12/3.6 = 3.3A, which seems like a good amount of current to do some heating. So I put a jumper between the two thermistor leads, which turned off the relay....

Velleman Thermostat Not Working
Hi, I have assembled the SeeMeCNC H-1 with the stock electronics, changing the R5 resistor in the thermostat as specified. I have been able to use Linux CNC to get the stepper motors working, but the thermostat does will not give current to the heating resistors. I checked the power input, it is get...
