General Mach Discussion / helix toolpath problem...

« on: May 05, 2010, 10:26:29 AM »

Hi,

Since a while I am having a problem with some helix toolpaths, generated by mastercam x4.

The problem occurs when milling a hole slightly bigger then cutter diameter, so with a small helix spiral.
For instance when milling a 4 mm diameter hole with a  3 mm cutter.
When the hole is a little bigger, say 5 mm the problem doesn't occur.

Actual problem: At the first part of the toolpath everything is normal, about half way the machine starts moving jerky and speed decreases.

Tried different cv settings, didn't help...

Anybody any suggestions?

Thanks!

Rich

Hi Hood,

Thanks for the answer.

I must admit, I did not do a forum seach... should have been able to get the answer by myself..

General Mach Discussion / driver watchdog triggerd?

« on: April 24, 2010, 09:24:01 AM »

Hi,

When I load a large engraving file (4,8 mb) I get then message "Driver Watchdog Triggered" and Estop is triggered.
Resetting the machine is all it requires, so minor problem...

Does anybody know why this happens?

Hi Dave,

Thanks for the schematic...

It will require some tweaking, but it indeed is a good starting point.

Next few days will be a litte busy  because of work. I will dive into it this weekend...

Thanks again!

HI Dave,

Yes, the concern is electrical. The toolsetter is a homemade device which uses an inductive switch.
The probe is a Renishaw MIP and a PI4 interface. The probe interface output can be either TTL or SSR (Solid State Relay).
This SSR is capable of switching only 40mA..

The LPT input is an optocoupler with a 24 V supply.
Because I do no want to risk damaging the probe interface I am looking for a way to connect the toolsetter and probe interface separately.

I was hoping the solution could be found in the software.
But, as you say, I am beginning to believe that some electronics may be necessary...
Some suggestions would be great...!

Thanks!

Rich

Hi Dave,

Thanks for the suggestion..but this is kind of what I use now...    

The plan I have is to make a permanent setup.
I want to mount the probe next to the spindle and lower it with a pneumatic actuator when needed.
No more touchplate, no more edge finding, no more vise alignment, just probe, do an axis rotation (G68?) in Mach.....and hit the START-button....

That's why I prefer a fixed setup...

But thanks for your time anyway!

General Mach Discussion / how to set up 2 probe inputs?

Hi,

I have a toolsetter and a probe and I want to connect them both to the Mach probe input.

From previous experiments I can remember that you HAVE to use the probe input in a probing macro, you cannot use another free input.
(Please correct me if I'm wrong)

Because of their construction the probe and toolsetter cannot be connected to the same "physical" pin of the LPT Connector.

So what I would like to do is to assign two pins of the LPT connector to the Mach probe input.
Is this possible?
Or is there another way to solve my little problem...?

Thanks!

Richard
