:? well, I've had some steppers working from the digiplan drivers using Mach 3 with, ermm interesting results... There seems to be a problem when changing direction, it appears that the direction pulse is rather sleepy and causes the motor to go rather crazy. It fafs around then runs fine as long as...

Ok, Ok, don't get too excited :roll: Just a heads up for today to let you know what’s coming, no piccys at the moment, just sorting out what I've got & how it goes together as it came in a box. I've made my Mk1 interface between the original digiplan stepper drivers (Thanks are do to davidimurray fo...

Sounds like a button problem - will it slow down?

Anyway you'd end up retro fiting Mach3 on it as the controls so basic by todays standards

not sure what you mean by software there as turbocnc is for controlling the machine (ok so it's sw) & VR sw is for making bits.

do you want something for driving the orac or a CAD CAM package? (drawing & making bits)

this might help......

No easy answer. Depends on your skill set

seach this site, Davidmurry has done a conversion on a starturn. that will give you a start

Google is your best friend

try Mach 3; gecko; breakout board;

bonne chance

Well......... The only bit that needs 3ph is the motor control - if you're good with wiring diags you can find the relevant offenders and change the inverter for a single phase in 3ph 230v out and you're sorted :) Oh and change the wiring for the motor to suit 230v easy eh?unless it's a Fanuc or hie...

for economy you can try rusty nails as well

I have been running a workshop in Montana

nice work if you can get it

So the pewter is poured directly into the mdf? I assume the die is a one shot die. How far do you fill the mould? - just to the top or overflowing?

BTW whats the melting point of pewter?

If it stops in the same place every time perhaps it's the code

just my 2 centimes worth

HI & welcome to the nut house

Google Mach3 that's the software sorted

& search this form, I believe Davidmurry has posted his conversion, seems easy enough

Spelling is not your strong point either then ? :doh: mitigating circumstances: 1. wine might increase your verbal fluency (in any language) but not the written word :roll: 2. It's a japanese word (I think roughly translated it means expensive parts) 3. The keyboard moves about after a bottle of wi...

There's a promimity switch under the cover just below the air ram, and as best I can work out is that it switches off the motor and hopes it stops in the right place! (well it usually works) If you can get it to do it once it doesn't seem that that would be the problem :? Go on tell us what control ...

does it change tools by typing in M6 T3 etc?
what control does it have?

can you post a snippet of the relevant code?

Very interesting to watch, what's next breaking out & machining video?

I wonder if an Antony Gormley bollard would add anything to our park

BTW no "a" in foundry (end of the vid) not very educational

perhaps it's your code

Have you tried with a DTI? do a prog G00 Z0 Z-100 Z0 Z-100...etc then finish with Z-101 so that it kisses the DTI (which you've previously setto zero. If it don't work at rapids try feedrates just to see if you can make it work. I'm sure I've heard that those drives do that when they start going duf...

Hmm, any backlash wouldn't acumulate. something loose maybe but still won't give 3mm of error - other than a pulley loose, also check the tightness/state of the belt & while you're there make a note of the size for future reference.

Cheers Traic Whizz

No worries, i see you have one of those dsylexic keyboards

Good job you didn't print the stickers for the machines

you can call me TW

Hi

after a long delay... ho hum, well I am rather busy at present...

Here's the latest version with Andy B's bit added in, (good work Andy) up to page 26 but some are missing cos I didn't have the print outs with me when I was inputting - I'll rectify that as time allows.
