Bob: Is it set to "autoZero the DRO"? This should stop the softlimits from applying when the ref is done. It shouldn't be possible to hit a limit with softlimits enabled as the softlimits should be

I have a new CNC router that I build set up to run. I am trying to figure how to back off a limit switch using software limits. If I go to the correction page and toggle the software limits, I can

It seems than when there is a direction change inside a single command (e.g. G02), there is no effect to the exact stop setting. For axample: G1 x0 y0 G2 x0 y0 i10 j0 In this case there is a stall

Steve: I will lookinto user settable index points. I was thinking of some sort of memorized points at any rate. In the end, whatever's needed will be provided. :-) Art www.artofcnc.ca

That may be the type of stuff you do, but we dont all have turret machines, or do that sort of work. If I was doing that I'd be DNC'ing via a high level commercial program - not using Mach2! Mute

Isak: This should only happen in CV mode, or if your acceleration is too high. Lower your axis acceleration to a ridiculous level to see if it does indeed decelerate and accelerate. Then make sure the

Bob: As yet, radius compensation is not active, nor is constant surface speed. Feed per rotation is implemented. Turn still has a very long way to go before anyone could call it complete, but it is

Rich: Nope, the CAM programs will work it out for you. Most safeties in this regard are used when a user is writing their own code or MDI'ing their way through stuff. I will try to take all thius into

Yes, but the majority of CNC lathe operations are centerline and inside tools. Typically I have turrets loaded with a 4:1 ratio of inside tools to turning or grooving tools. Most operations don't even

Art, I explained what the trade considers "Z safe" in a response to Steve. It's just a safe place to index the turret during program execution. The actual position is established in the program in a

Am I being dumb or overtrusting, in expecting MasterCAM/whatever to work all this out for you? Richard

Not when the world is full of litigious Americans ;) I am aware of that, I'd already assumed you would withdraw the tool from the stock - the problem can arise with Mach2's compound moves. Once it's

Great stuff - looking forward to a repaired version. Next headache threads ;) -- Steve Blackmore

Hello Mika, No question, go with the higher sampling rate. I started with a 20Mhz and now I have a 100Mhz looking after a 200Mhz. The reason why is because the osciloscope is a tool to "see" what is

Art, There's a limit as to what you can do in software for safety? If my OD tool is in a groove (or behind a shoulder,) i must do X+ before I go to TC. If the tool is inside a bore, i must go Z+

If the start and end aren't equal, it's not a circle/arc. What cases would those be? dg

If you can afford it get the HPS-40. The main limitation on any scope is the sample rate. Eventually you will want to debug a problem that requires a higher sample rate. The other reason is that

That can be be sorted with Z inhibit (not the same as Safe_Z) The problem with turned parts is they often have grooves, or diameters smaller at the chuck end, (nearer to Z0) - this is not a common

Hi, I need some help from experts. I have possibility to have handheld oscilloscope from Velleman. There is two models: HPS10 and HPS40 The difference betveen these two is maximum sample rate ( 10MHz

Isak, could you elaborate? Is it occuring in constant velocity or is exact stop the problem? Just curious, have never tried exact stop. Frank Carpenter
