Re: Tool clearance adjustment between each pass when turning

The simplest way is to upload to Youtube and link to it from here. It's pretty quick and easy.

Perhaps you could post the code that is generated?

Re: 5 Axis simultaneous? Fusion 360 Machining extension

Be aware that Uwe is paying for the "extensions" that cost several times the licence price. For those of us without the appetite for such an expense, we are stuck with 3+1 operation, which the std Centroid post processor supports fine. 3+1 allows indexable 4th axis work ie move the rotary ...

Re: New Build: Another Techno Lathe

Be aware that if those wires are going to be seeing movement as the table moves, they need to be flexible. Cat 6 cable may fatigue fairly quickly and fail weeks or months down the road.

Re: Offset problems (I think!)

TBH, I'd be pleasantly surprised if you have only 14um backlash on the X axis, looking at the machine construction. If you approach a gauge block or ring gauge with a DTI from opposite directions, then subtract the gauge width and DTI probe tip width, you should get zero difference. That will likely...

Re: Power Drawbar Safety Mechanism

I use the "spindle stopped" signal in conjunction with the spindle top switch to enable the drawbar. That way it can only operate when the spindle is fully retracted and is stationary.

Re: Tailstock IN / OUT - M78 etc - RESOLVED

Seems to require the PP to be edited: // fixed settings var firstFeedParameter = 100; var gotSecondarySpindle = true; var gotTailStock = true; // changed EME 25/3/2023 [/b] (This tells the PP that you have a tailstock) .... function getCode(code) { switch (code) { // case "PART_CATCHER_ON"...

Re: Tailstock IN / OUT - M78 etc

The macros seem to be M32 (in) and M33(out).

Tailstock IN / OUT - M78 etc - RESOLVED

I'm trying to post process some CAM from Fusion. The workpiece is fairly long and thin, so I need to support it using the (hydraulic) tailstock. Fusion has a tickbox option for tailstock support ("use tailstock") in the profile roughing and finishing operations. These are said to generate ...

Re: Auto tool setting

The OP was asking about tool length offset on lathes. It felt to me that the most consistent method was to use a reference tool (tool #1 in my case) to set the reference X and Z, then measure the new tool(s) relative to that. This way, the effect of runout is minimised (assuming you don't move the s...

Re: closed loop with Acorn 6 and a linear scale

There are long boring discussions in german forums how to integrate scales in other CNCs, with Centroid it´s a 15min job if you are slow :lol: Uwe Haha yes, I have closed loop controls on my other (LinuxCNC) lathe. It was "a learning experience" but some features don't work (eg conversati...
