ZASto,
Thanks for the second link to isoplotec.
I tried the link initially, but it came up "Forbidden", and I exited to do other things.
When you linked it a second time, I realized that you...

In a recent Thread I asked for help in identifying an old (approx 1995) router:

The Thread has got some...

A friend has acquired a very well made router with steppers from the 90's.
No manual or operating instructions.
Used in a production environment to engrave laminated plastic labels.
Out of use for...

Spent a lot of time to determine the old ball size was 6.365 mm.

Loaded the nut with 103 old balls plus 3 off 1/4" commercial balls.
Clamped the screw to a mill table using V-blocks with a DTI...

Did a test with the nut clamped horizontally in the vise with approx 500 mm of the screw on either side.
A DTI shows the screw has +/- 50 micron vertical looseness at the ends.

This possibly...

I have a THK 3210B ballscrew off a turret mill X-axis in pieces for cleaning.
The balls are 6.365 mm (as measured with a precision DTI on a test stand calibrated against precision blocks) and...

Thanks for the clue.
Launched a trial (free) version of Canbam, chased down the Post-processor and found the fields you describe.
Thanks you very much.

My local mens shed has an Arduino router...

Some CAM products allow a file/storage/window to allow entering and to retain Pre-amble and Post-amble Gcode that is combined with the Gcode file produced.

Can Cambam do this ?

Mike,
Thanks for the offer, but I have solved the problem.

ger21,
I appreciate your comments about developing software.
It is just that I have been in contact with computers since 1969 with...

Well, I found out the hard way.
I have operated DraftSight V1R5 (or R4 ?) on my Dell laptop under Windows XP for a couple of years perfectly OK.

Then, the backlight on my laptop died, so I added...

Alex,
Thanks for the comments.

As previously stated, I will have external E-Stop buttons and these will provide absolute power isolation,

The question in my mind is, should the external power...

I am new to CNC with a stepper driven mill acquired without any external E-Stop buttons and currently being re-commissioned.
I will implement external buttons.

Neil,
Contacted Leadshine and got an answer in 1 day from Paul, an Applications Engineer.

Paul confirmed you get a coasting stop when ENABLE is reset (0 V dc).

Paul did not add any comments on...

Neil,
Does the driver simply stop pulsing with current at zero, or does it do some sort of powered braking action ?

I have never operated a CNC mill, so I have no idea how far a spinning...

I am re-commissioning a newly purchased Bridgeport clone turret mill using EMC and MD882 to Nema 34 4-terminal steppers.

As acquired, there is no E-Stop facility.

The MD882 has an ENABLE input...

My Kondia FV-1 has 3-axis CNC added by a previous owner.
I am currently re-commissioning and checking carefully as I go.

Al,
Dismantled the motor and found that the cabling to the terminals are single tinned copper cores disappearing down into the middle of the winding.

To get at the coil connections to the copper...

Al,
I disconnected all the external wiring at the motor.
All 6 terminals test as connected.

I took one internal connection off a terminal.
The core(s) are stiff like it is the actual winding...

Al,
thanks for comments.

The motor is rated 2.5 kW/1.5 kW, near enough to constant torque.

High speed is star:

- terminals 1, 3, 5 connected together.

Hi all,
The Kondia Powermill FV1 that I have just acquired is fitted with a 415Vac 50 Hz 2-speed motor.

Has anyone had any success re-connecting the internal windings to 240Vac ?

The motor has...

Hi all,
