You should have many documents already installed on the control. A lot of programming was by experience and trial/error using the pre-loaded stuff. It told you where...

Your PC needs to connect to the machine's IP ... ours uses WAN settings
Your machine has to be open to allow connection

Just a couple of questions....
Is stepover of 0.6mm correct ???

... what axes does your machine have ?
... on what diameter is the flats ?
... size across flats ?
A little sketch would help.

Another option may be the later software TNCREMO for transferring files via ethernet.

All this was addressed in early CNC evolution with the machines capable of "cutter compensation".
Program it once, .... then adjust the toolpath by a value held into the offset field... at the...

Ok ... can you guys explain this link
https://ezdxf.readthedocs.io/en/stable/concepts/units.html
This was seen in various docs explaining units, so I am assuming a generalised example.

Yes......

Nah.... I dont believe this. It does know what units the DXF was created in.
If I do a CAD drawing of a 1" cube, export a DXF
Now open that DXF into a different CAD system (default is millimetres)...

Mill it using C axis ....
Basic lathe operation is to be turning diameters only

Check your leadscrews, it could be the connection between it and the motor, or thrust bearing end play.

May even be play in leadscrew nut(worm ball bearing).

Try turning/moving by hand with...

Only guessing
You have an A output(around X) in the programming... but you have a B axis (around Y) in the machine configuration.

I think Craig thinks you are "driving" your machine from the DXF file...
DXFs are created in position & size with the originating CADware.
It is in your software that you need to adjust the design....

I would think it was a panel push button, or M code to turn ON and a different M code to turn OFF.

You may have to enable "milling mode" to interlock C to the handwheel.

Too fast (aluminium speeds), you are rubbing, not cutting.

Try 65m/min (S3500), & feed of 0.05mm/tooth
Neat oil may also make the cutter slip, not cut
Soluble oil @ 6-10% concentration

Make a stepped bung to fit in the end, and if the OD is not to be machined... make soft jaws to avoid damaging the finish
You could also make a stepped bung with centre for a tailstock centre.

You can purchase gauges for a dedicated range (ie... 0-1" or 0-25mm)
Or obtain sets for a larger range (ie... 0-6" or 0-150mm)

G17/18/19 plane change only affects circular interpolation (the axis of the arc is perpendicular to the selected plane)

You have an air outlet & outlet at the top, & a drain line at the base. It appears to be a filter with a water separator.
The item with the dial is a regulator, it seems to have a fill level gauge,...

Any machine can maintain a good tool life...
The BIGGEST killer of any & all tools is the programmer, tool setter, or the operator, (they may be the same person).
Looking after your machine & tools...

Ours is heidenhain control..
You need to input an approximate length into the length offset to avoid that alarm..

I have a basic tool measure program, all I change is the tool #, and RPM (...

Might be easier to program the path that the centre would perform...ie. path is 6mm offset from the part profile
No need for cutter comp
No need for P values

Back to your issue... P value might...

Nah, not a silly question....
They have a thread to allow various forms of extraction.
(ie. Screw + washers, pulling the pin thru a spacer.... or, to allow use of a "slide hammer").

Pins are...

I assume your MC7 is v7, not X7 (seeing that you also mention X5)
It is a big gap, what.... 30 years?

Thanks Rader for reposting the images, makes a big difference. I dont think I will ever switch to Arena, I'm that close to putting my feet up, old habits die hard and stubborn as hell, and i dislike...

I'm currently on leave, so no access to CAD.

I know it can be confusing, but I started doing manual unfolding using CAD.
IE... R1 on internal bends, 4mm plate (external bends=R5), (K-factor of...

You cannot have more segments than bends
1 bend gives 0 segments
4 bends give 3 segments
12 bends give 11 segments, the lengths before and after the area of bend are not segments
The number of...

Possible maths error ???
... you may have issues regarding # of bends verses # of segments.... 10 segments = 11 bends, or if you want 18° bends for a 180° return, which is 10 bends or 9 segments...

Forgive my ignorance...
Should your folded model be drawn true and correct.... then unfolded using a k-factor

Seems as if you are trying to use SW as the bending machine, instead of designing,...
