Denford easiturn 3 lathe
Faulty PNC3 controller not working but lathe is mechanically fine, ideal for some who knows their way around the electronics or conversion to Mach3,
Lathe has the auto toolchanger option and rear tool mount, so possible to have 9 different tool set.
There is a chuck and ...

Cheers
I will have a look, but first I need to move it away from the wall.

Hi
I have a Easiturn 3, I was using it the other week, when the power just tripped out.
I reset the power supply to the machine, and the auto toolchange unit came on, but the rest of the machine is dead.
I check all the fuses in the control, is there any other fuses in the base of the machine I've ...

Hi David
I think it came down to taking out the small rapid moves and changing them to fast feedrate moves.

Not sure if all of these machines do the same thing, but this worked for me.
I couldnt find any fault with the x axis, all seem fine.

Hi
Have you any of the main electronic boards left for sale for the Easiturn 3?

Hi Bill

I bought a Easiturn3 with auto tool changer about a year ago, its not a bad machine considering the age of them.
But a few things that could be better, like the axis movement is not that smooth and seems to dwell between each movement.
Screw cutting can only be cut once, if you try to re ...

As anyone replace there drive belts (1x main spindle and 2x stepper motor to leadscrew) on Easiturn 3 Lathe.

Any part numbers available? or do some one know where I can get these from?

Do anyone know where I can get a NEE PNC3 control from a Denford Easiturn3 repaired or replaced?

I have emailed, phoned and left message with North East Electronics but no reply are they still going?

Just checked all the wiring from control to the Z axis stepper motor all seems in order, checked the grey ribbon cable from driver interface board to the main circuit board seems fine.
I swapped over the stepper motor cables on the driver interface board (4 wire plugs), so the X axis drive circuit ...

Just checked the stuff you pointed out on the PLC, It was just a bit of the backing stuff from the mosfet above it.

I have just notice that on the axis drivers interface board(the board the two drivers plug into) with the two large green LED's which you can only view from looking down from the top ...

Hi Russell
If you have any issues connecting up, or formatting your Ind editor, I could forward you my parameters.
I have an old dell cpt330 laptop(win2000) connected to mine for tranfering progs.

Hi
On either of the drive boards when in the Z axis slot light up green when first powered up. then when homing out, leds switch off.
when home position is achieved the green led lights up (thats what the X axis is doing)
This is not lighting up on the Z axis board because home position is not being ...

I double checked the ribbon cable seems to be clip in fine at both ends.
I swapped the drive boards over, no different, X axis homes out ok, no movement in the Z axis as before. I suppose thats one good thing drive boards are ok.
I noticed while the machine is trying to home out the Z axis stepper ...

Hi Martin
I have just checked what you have stated.
I think the X axis is working ok.
All the limit switches (4 off) and home sensors (2 off) seem to be work ok on the 'T' screen.
when I powered up the control, the two drive boards have green leds on, all red leds are off.
seems the Z axis is the ...

The error states 'Motor drive fault in X'

Hi
The easiturn was running fine, the next day, turn on and tried to zero machine out, X axis moves to home position (moves back and forth)
then nothing. screen states homing is in progress. Z axis does not move.

By pressing 'E' stop, shows up X axis error.

Right I have taken off the X axis drive belt cover and have turned the leadscrew, while the 'T' screen is showing. The datum senor seems to be working, show 0 or 1 as I wind the leadscrew in and out.
Could the error Im getting be the micro switch?

Hi
Just wanted the comfirm the location of the X axis homing sensor.
from what I have read, I will have to take the cross slide off to access the sensor.

Is there anyway of checking the sensor before getting my tools out.

I have done the T test, but cant move the X axis manually to make or break ...

Thanks for everybodies input, I have got the tool changer working again!
For future reference for anyone, the problem ended up being corrosion on the circuit board, I gave it a clean up and seems to work fine.
Also if anyone wants the timing position of the timing disc, I can forward a pic and ...
