Hi,
Been using Mach3 for many years first with a Taig and recently with a Tormach. I recently purchased a used Marposs Probe to replace an econo probe I had for years. The Marposs probe came with a probe tip that is 0.2755" dia. But when I put input this into tool #99, the message of "probe tip diameter is invalid " comes up when I try to probe the vise. I can probe X, Y or Z just fine but not the vise. Can anyone help?
Thanks!

Are you using the tormach system? If so then it is different from a standand mach setup.A standard Mach ssetup does NOT use Tool#99 for tip comp. There is a setting on one of the pages that comps the tip and then ONLY to comp the saved points files.

Yes, I am using the Tormach provided version of Mach3. I thought they were pretty similar with some addons and pre-configed for Tormach.
As for the special screen you are talking about, is it the offset screen? If so... the offset screen still updates the tool table... right? Tormach recommends using Tool #99 for probe but you can pretty much use any # you wish.
Thanks for your help... I might have to give Tormach a call... was hoping to get it working tonight.

It seems the probe tip parameters are set in the Tormach screen set. Just found in PCNC1100M3-W.set where it sets the min and max for probe diameter.
If ProbeDia <0.1 OR ProbeDia > 0.25 Then
Message "Probe tip diameter is invalid"
But when I tried changing the 0.25 to 0.30 and restart Mach... it crashes with a white screen (tool bar on top still there... can click on it, load a file but the main screen remains white... when I try to exit... Mach crash message pops up)
Anyone know how to change the screen set correctly?

Can you attach the screenset please.

Thanks Hood... attached is the screen set. There are 5 places where the ProbeDia comes up and I tried changing all 5 to > 0.30 but as soon asI make any changes... Mach will crash.
Thanks for helping.

Do you have the bitmaps for that screenet or a link to the download as I dont see half the screen.
Hood

Attached is the bitmap folder. Thanks!

Where is the probe dia set up, must be getting short sighted ;D

Took me a while to find it as well... I ended up using Search on notepad and searched for Probe Tip. This is a cut and paste from the first one... the other 4 is very similar.
If DistToLook < 0 Then DTLSign = -1.0 Else DTLSign = 1.0
UserTool = GetOEMDRO (824)
SetOEMDRO 824, 99 ' select probe
ProbeDia = GetOEMDRO (43) / Mmm ' stored in inches
SetOEMDRO 824, UserTool ' revert to users tool
If ProbeDia < 0.01 OR ProbeDia > 0.25 Then
Message "**** Probe tip diameter is invalid"
Exit Sub
End If

Which buttons are the scripts in?
Hood

Found one in the vice jaw button and changed it and all seems fine, where do you actually tell Mach the probe dia though? Is there a DRO in the screenset?
Hood

I wonder if the screenset is protected in some way, I changed the VB and exited Mach then when I started up again the screenset was not loaded so I had to reload, checked the VB and it had not saved.

One thing I just noticed... If I change anything in the file and save it... even if I change it back to the original... that PCNC1100M3-W.set will no longer work!! Below is what I did to test.
1. backup/copy PCNC1100M3-W.set to PCNC1100M3-W.set.bak
2. open PCNC1100M3-W.set and change only the first <0.25 to <0.30
3. save file
4. change back the mod from <0.30 to <0.25
5. Save file
6. Start Mach and it crashes.
I can rename the PCNC1100M3-W.set.bak to PCNC1100M3-W.set and the original file will work.

Probably best contacting Toirmach and asking them how you can change the tip dia
Hood
-
I think it might be protected somehow like you said. I just tried changing the date and time back to the same as original file and that did not work. This sucks. I already called Tormach and they said they will put it in as a suggestion to increase the probe tip dia and I will have to wait til the next release which will not be for a while.
Ken

Not so good :(
Hood

Would it not be easier to just change the probe tip (;-) Last I heard you can get Tormach to unlock your screenset BUT from that point on you are on your OWN as far as trouble help.
Just a thought, (;-) TP

My Mach is unlocked... My warranty has been over for a few years so it didn't really matter to me. I'm trying to find out if unlock gives me access to screen sets. Anyone know?
As for probe tip... I've searched everywhere for them... but no one seems to sell them. eBay has plenty of Renishaw Stylus but not Marposs. Marposs uses a M4 0.7tread and Renishaw has some stylus that uses a M4 but not 0.7 Tread so they aren't compatible... I found out the hard way. I've got 2 Renishaw Ruby tips that I can't use.

I see 4m x .7 just about everywhere I see aftermarket probe tips listed ???
(;-) TP
-
Can you provide me a link? Love to get some. Thanks!
Ken
-
ANother thing to think about is a 4mm X2mm adapter that way you have access to 2m type tips they seem to be cheapest and most popular.
-
Thats a good idea. Do you have a link to M4x0.7 stylus or adapter to M2 tread? Thanks!
Ken
-
Look in MSC I just saw them there for about 29.00
-
MSC # 08582678 and 93034809
That will be the best bet the other 4m stuff is a bit expensive.
(;-) TP
-
COOL!!! Thanks! Did not know MSC sells stylus! Just put in cart one of the adaptor and looking through the probe stylus now. Thanks man!! You save me from shelving an expensive probe!!
