sorry jonathan id totally forgotten about the above post.
Ballscrews fitted,steppers fitted,its almost there.

Ive made a start on the electricals /enclosure (photos will be up soon) and decided to go for the DG4S-16035 positioning DC servo drive and a BRKC-180 braking circuit to power the spindle motor..i had come across a few on the zone using these on there mills with no complaints

im assuming the heds encoder/blue ribbon will need to be rigged up to this DG drive via one of these differential line drivers in the link http://cncdrive.com/Difflinedriver.html.

Had a poke around the spindle motor area took off the wiring cover to reveal the connection block.
the block is printed with he following wire colours to each letter
T1 RED
T2 BLACK
K1 RED
K2 BLACK
A1 WHITE
A1 BLACK
B1 RED
B2 BLACK
.edited i completely missed the pin out info on the back of the lid so will stick below as I couldn't find it on line edited..what are the K1and K2 wires with the T/0 below it ?

second question I have is..
with me using the heds encoder and plugging that into the dc servo drive as the manual instructs,
is the optical sensor that sits on top of the spindle and the tach no longer required??

I don't understand why I would need 3 forms of feedback yet they were all installed as standard when the lathe was in its original state.

It turns out I don't need to be concerned with anything other than the encoder so I don't need the rest
im on the wiring next,it wont be pretty.


ive no experience with electronics but I should be ok with wiring the drives getting the motors moving etc
one thing im struggling with and cant find info on is the tool turret card and the 24v solenoid that operates the turret lock and how/where I would go about wiring these into the pmdx 126 board.
EDITED Found the info for the board

..what are the K1and K2 wires with the T/0 below it ?

thermal overload, over temperature probably

[dazza]

right apparently I can use the k1 relay on the pmdx board to work the turret solenoid .
does the wiring from my turret board to the pmdx look ok in the image below?if so can/should I daisy chain the grounds on the pmdx?
Ive also received an email telling me as the lathe has a turret I will need either a smooth stepper or a second parallel port.. so im thinking this if anyone has any thoughts on it.http://www.cncdrive.com/UC300.html

Not sure if the PMDX is common gnd (Edit: Looks like it is) or if the 5V Gnd is isolated from the inputs.? If common gnd it will use the 5V supply Gnd as it's potential ref so won't need jumpers. If not then you will need you to connect the Input Gnd's to 5v supply Gnd's. In either case won't hurt to daisy chain if unsure.
Same if you use external 5V or 12V you will need to reference Inputs to that supply's Gnd.

Hi everyone, diesel were you able to successfully complete building your dm3000? I purchased one a couple months ago and am in the process of converting mine to mach 3 but I wanted to ask you a couple questions if you don't mind.
