DDCSV1.1 4 Axis controller
Joules:
Turns out my bad stepper was a bad delrin nut, it had tightened up and stalling the lead screw. Heated the alloy carrier to 155 ℃ and cycled the leadscrew, freed it up a treat. Just had to re loctite the nut in as the heat had released it. Had a thermocouple in the carrier so I knew what temperature I was at. Now flooding the bronze bushes with oil as they got dried out as well.
I also sussed out how to send XYZ to my zero position from the controller before shutting the machine down.
:D Looking good
Pete.:
You have managed to glue Delrin nuts into a carrier with Loctite? What grade was it you used? I had to pin a Delrin nut to stop it slipping.
Joules:
In that case Pete I will wait till morning and see if it falls out. I think if the nut has a less than perfect finish in an unpolished bore, the loctite will probably hold it pretty firm.
The loctite in question was some clone product from the local farm shop used to glue tractors back together :lol:
John Stevenson:
Joules,
That setup is looking very impressive. I feel we are rapidly getting to where the hardware is advancing faster than software. Bit in the news today where Intel are stopping development of the Atom chip and concentrating on the ARM chip.
The unit I have just shipped in from China whilst only being 2 axis as its for a lathe can handle encoders, tool turret, coolant, spindle, Chuck and oiling. It's basically a Fanuc 0T clone for sub £400.
We live in interesting times
Joules:
Pete, just done my testing and running the Z into each end stop, the nut is well fixed with my loctite. Pretty sure its all keyed into the imperfections than physically glued the Delrin.
