Thread: Emco PC120 Turn
I bought one of these last week and it was delivered yesterday. It was sold with a faulty Mach 3 PC. Long story short, managed to get it running. I had issues with the spindle, that's now running but needs some tuning.
There is no spindle encoder working, some loose wiring, will sort that at a point.
The board to control this is unknown to me. Ive got some pics, will upload it. Its a parallel port setup. If it works reliably, Ill leave it.
I need to get the tool changer running, I was trying to use M6 codes last night but was told that I need to use T101 etc.
Then its understanding how to deal with the tool offsets although with numerous help vids around, hoping that is not too tedious.
I am looking for the tool holding plates that told tools in the tool changer as well as the bushing that is use to hold boring bars / drills in place, does anyone know where I can get some of these? I could make them but easier to buy to get running.
Not a large cutting area but a nice machine and fairly well converted previously.
Also. Does anyone know if the chuck (manual scroll, not the pneumatic one) is reversible? I tried to use the outer clamps (reversed) and it wont screw in.
Have a read of the Mach3 turn manual, as it explains tool offsets pretty well.
The one thing I will say, is they're far easier to handle if you have accurate homing on the X-axis (Z axis is less critical as you can just bump of the end of the stock).
With mach3 you want to be using the Txxyy format, where xx is the tool position, and yy is the tool offset to use. It's meant for turret setups where you swap tools in each position.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
The machine has proximity sensors, so I think reasonable accurate (hoping).
So T101 is tool 1 using offset 1? Is the offset captured in the tool table?
I always used 4 digits T0101 for clarity, but yes that will command the turret to position 1, and load tool offsets 1 from the tool table. It's the same as using T01, but I always preferred the 4 digit version for consistency.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
A quick and easy way to check is that the teeth which engage the scroll will have symmetrical inner and outer faces if the jaws are reversible,
- NickIf you will not be swayed by logic or experience simply pick the idea you
like best, but ask yourself why you sought advice in the first place and,
for a simple life, perhaps consider not doing so in future
ATC works. Got an idea how to do offsets but not sure how you 'centre' a drill.
The spindle is being given controls via RS485. It doesnt work on power up. Enable the plugin for the VFD, it works but trips (kicks out reset on software). Then disable the VFD plugin, it works without a problem. That said, it spins the wrong way initially then the correct way. The speed inputs also dont seem to work well. Might need to reset this setup and start again.
