General Mach Discussion / Re: Moves in x direction before step down

I rejoice with you.

But I am still wondering why your gcode ran perfectly on my third-party simulator.
There could be some settings within Mach3, that the gcode generated using the old template, that may have caused Mach3 to crack. Did the new template just papered over the crack?

Further checks in Mach3 configs.
Is your Lookahead = 200 lines or just 20 lines?
What are your settings under CV control?

'Alternative Probe z surface macro 
‘Test probe is working first before using this macro

FeedCurrent = GetOemDRO(818) 'Get the current settings, OEM DROs (818)=Feedrate DRO
ZCurrent = GetOemDro(802) 'OEM DROs (802)=Z DRO
GageH = GetOEMDRO(1001) 'OEMDRO(1001)=Gage Block Height
ZNew = ZCurrent - 6 'probe down max. 6 inches

I am new to the forum new to CNC and new to mach3 so here I am.
I bought a machine and I am now trying to configure mach3 and I am moving along slowly and having troubles with my probe/ touch plate.
Right now I am looking for a new script that will enable me to use the touch plate. The one that I got from YouTube seemed to work but it would send my spindle 6in off the material surface and when I tried to run code it ran the code 6 in off the work surface. So I want to find a new script and see if that was the issue.
any and all help is appreciated and I will do my best to learn to navigate the forums as soon as possible thanks for your patience and help.
I am in the United States. Mid Michigan to be exact

Attached is Tool Probe VB code I use (but I use with Parallel Port).
You need to change 2 Z values to suit your plate thickness and retracting height (commented in RED)
Or get the idea and edit the code you already have.

Share Your GCode / Re: DELRIN

Not sure if this is the correct place for this post ?
Looking for advise on cutting Acetal / Delrin 12.5 mm thick . I im getting reasonable results at 20mm per second at 20,000 rev per minute 3 passed last pass .5 offset with a 6mm twin flute bit but Still minor chatter marks on the edge. The work piece is held down well so maybe a different cutter or feeds and speeds need adjusting ?

Too slow
Use calculator @
https://pub.pages.cba.mit.edu/feed_speeds/
Delfin chipload is listed there too.

(sorry calculation is in imperial unit)

Mach4 General Discussion / Re: incremental mode, absolute movements in cycles

« on: April 02, 2019, 05:49:57 AM »

FYI: See G82 of FANUC (attached)
Z is absolute

G82 depth is always absolute
G91 (incremental mode) will allow shifting x & y incrementally so you can drill multiple holes using G82 canned cycles.
(info is from Fanuc as I think Mach4 (unlike Mach3) is following Fanuc very closely)

your subroutine call
N17 M98 P0001
is missing an L parameter
e.g. If you call subroutine 2 times,
line 17 should be
N17 M98 P0001 L2

Please increase your Mach3 kennel speed from 25000Hz to 36000Hz or even 45000Hz if that is possible.
(MACH3 Demo version users are limited to 25000Hz)

Hi,
really, pages 7 and 8 of the Mach4Lathe.pdf...

Craig

Exactly what I am saying.
Only G76 does NOT have "*" mark
It means G32 G34 G35 G36 are ONLY available if you pay $1,400 for the Mark 4 Industrial Version??

Hi,

MACH4 - Does not support G32 only G76

Incorrect, Mach4 supports three Gcodes for threading, g32, g34 and g76 as detailed in LatheGcodeProgramming.pdf
in the Docs folder.

Craig

Craig, you are only HALF RIGHT
Copied from the Doc...
G32 1 Threading* N 31
G34 1 Variable Lead Threading* N 33
G35 1 Clockwise Circular Threading* N 34
G36 1 Counterclockwise Circular Threading* N 34
Didn't you notice the * marks?

It means Mach4 Hobby version users will have only G76.
