General Mach Discussion / Can Mch run more 'professional' machine

« on: May 10, 2008, 07:27:21 AM »

Hello
I am thinking about transforming my old mill to a powerful cnc, i already bought mach3 for my hobby cnc, which is run with g201, but the problem is when i try to mill Steel.
I wanna transform my machine so i could use mach. Mach works fine with the gecko drive, and i think it would work fine with the g320, but i am not sore it will be strong enough.
Does anyone have any experience fitting more powerful motors with mach, and what kind of electronics did they use.

I hope i did not go to much of topic here

I am using gecko drive g201, which have 10 microsteps. i think that it probably loses a micro step here and there.

Mach 3 is not closed Loop? i do not understand that, does that mean i cannot fit encoders on it?
I was looking at ports and pins settings in the program and i found some input pins for encoder a and b pulse, what does that mean that i can hook encoders on but mach will not correct if a pulse is lost?

I am sorry if i do not See the obvious.

Hello
I know this will be a little of topic, but i dunno in were should i post this.
Had anyone got any problems with machine keeping up with the steps? I am using a gecko drive and a 1.8°stepper motor, but when i was cutting wood, it seems to louse a few steps.
I do not like that, and i think this could be solved with encoders.
I was loking on the internet and when i was searching for some cheap encoders the most cheap ones i found were 100€ - 250€ so that is too much for me.
Does anyone know were i could get some cheap encoders wich would have a resolution of 400-500 resolutions per turn, or is the most cheap way to build one my self?
i found a link on optical encoders and i think it would not be so complicated to build one?

General Mach Discussion / how the helll do i calucalte m steps per unit????????

« on: April 29, 2008, 10:57:30 AM »

Hello
I am  runing in to a bigger problem than i thought, i cannot calucalte my steps per unit.
I have a spindel that moves 5mm per turn. i havea stepper motor that turns 1,8° that means 200 steps. so that should make it 40 steps per unit.
i put my settings to MM. but when i try to move for 5 mm of mesuerd value the machine moves for 50mm in mach. I have a G201 and all of its settings are default.
When i tried to calculate the movment it was around 533,33333... What to doo? ia am loosing my mind

My question is, why can't i order a calculator(titanium ti-89) in us and get it shipped to slovenia?? i am realy busting my head over this...
i wanna do this couse in slovenia this calculator costs 266euro in us it is only -150$
1euro is 1,46$ so that is 388$

So if anyone can help me i would be grateful.

chaoticone what you mean sreen 4 like a program, couse i have 0 experience in programing with visual basic.

Brian it is true i can set step per unit, but the defult units are mm or inch, can i set anyvere degrees, couse it would look nicer.
