this is the code i used to cutoff the ring ..

G00 Z10.0000
X0.0000 Y6.8000
G01 Z-5.000 F150.0
G17
G03 Y-6.8000 I0.0000 J0.0000
Y6.8000 I0.0000 J0.0000
G00 Z50.0000
G00 Y0.0000
M05
M30

now it occurs to me this should be reasonably simple to setup in mach as a macro that will popup a dialog box and ask me for Green = ((Fingersize/2)-(Cutter Radius)) and Red = (Depth below Z0) then run that code?

*cough*   

someone noticed my hub was off center.. yup i blew it, i forgot to probe the tool that cuts the keyhole and its shanks moved my wax .. thought i could get away with it.. but fellow jewelelrs eyes are too sharp.

recut the job.

 

if ya gonna do it.. do it right i suppose!

center of the hub is set as offset in mach.

been making more fixtures...  this one locks up a model after three sided cutting so i can cut away the inner supports.

(note: the hub id off centre.. i screwed up the path but i think you get the idea.)

i tried to use the cut circle wizard in Mach but it seems locked to IPM and inches for size not mm, even tho my mach is set to use mm. ??

i put in 50 as a plunge unit and it shot down to my model at super speed, so im guessing its 50 IPM not 50mm/min?  i have no way to tell from the wizard what the units are.

ended up coding a circle cut so i can trust it.

General Mach Discussion / Re: Really need help

To my mind the driver test is there to weed out the really bad computers that have no chance of running Mach in their present state rather than saying it will definitely run Mach.

Hood

You may view it as a pass/fail, but it also 'grades the papers' so to speak, and provides what appears to be a benchmark useable as a guide to setting us Mach. The logical assumption, and the one that I myself made, is that a passing grade at XX khz is a green light to set up for that speed. This is where the problem lies. Another area where the 'sin of ommission' is committed by the Mach documentation. I discovered that the driver test is not neccessarily indicative of how fast Mach can run on a given computer only after much wasted time and frustration 

Info worth sharing, methinks.

bit late to this game and very left of centre... but.. i did an install of a Minitech Mill with Mach3. SAme mill as mine, same software, and guess what... complete balls up.  the drives were hooking and jumping or stalling.

I went through the usual suspects.. driver test said ok. cabling was good, no other spurious signals coming from anywhere as far as i could tell.. I was at my wits end.

I happened to do another drivertest and it was fine.. left it running while i was lloking for a way to tell this customer i thought the controller was a duck. drivertest suddenly went to fail then jumped back. noticed it happened as customer moved the mouse. it would work fine until the mouse was moved then would go to fail mode. completely bizarre. further testing revealed that ANY other activity on the pc would cause this behaviour even at 24K rung up my mate in the US and his first question was "is it an AMD?", it was, then next question was "is it a newer one, multicore?"  yes again.

he suggested taking windows over to standard install from acpi, and lo and behold. worked perfect after that, even at 100K kernel.

soo.....   never overlook even the most bizarre bit of hardware that can be interfering with mach3 signal. subsequent reinstalls onto different machines at my place i have follwed the mach optimization rules document. never a headache since. install - plug - cut.

simple.
