General Mach Discussion / Re: CNC4PC C11 plugin for Mach3

« on: July 11, 2019, 01:45:46 PM »

No ESS used on my system Tweekie,Craig. All I have is the C11 Board.
When I bought my lase it came with a 'Laser control box' which had switches as shown in the picture attached.

The first thing I'm asked to do is connect my Breakout board to my ESS (which I don't have)

Maybe you could look at the PDF attached,as you say I may have to purchase an ESS Smoothstepper from Warp9

Not sure of the question Tweekie. All I have is the C11 board.

Ok Craig, many thanks. Now I'm going to be really rude and also honest. I'm not sure about this 'port switching' thingy! I have been following a guide written by a friend in George in Ausie, a transcript is attached together with a guide that I thought he had written, in my foolishness I thought it was one and the same person, turns out not.
I have attached a PDF with some links and files, I really would like to clear things up and get this device working as it was very expensive.
To sum it up! I have Msach3 R3 043.063
Aspire 4.5
CNC4PC C11 parallel port break out board.
If at the end of the day I have to go to Warp9 ESS then so be it! for the moment I want to see if it run good with what I have.

George talks about external PWM addons I'll have a look at ESS and see if it is incorporated onto their board.

If you find time to read through George's messages I would be extremely grateful to you.

OK Craig, so now what. Is my system junked ??
Where do I go from here ?

Attemting to configure Mach3 with an Endurance 10Watt+ Laser, a friend tells me to Select 'Plugin Control' then
Mach’s Menu->Plugin Control ->Spindle,THC & Laser Config:
I'm told to place a check next to PWM and set base Freq to 1000Hz and make sure ‘XY PWM Output’ is blank.

However I have no access to this screen, because when I select ‘Plugin Control’ all I get is a Drop down box showing  text for ‘Video Windo’

Do I need to add a Plugin

Clear! Thanks Craig,
Those Vexta's are serious stuff, and pricy. I have seen 5phase with driver (Used) at £145.00 ea but I don't think I want to go down that route. I have been using my machine as it it for 8 years or more with no issues and have created some very nice work (Se sample)
With the plan to install a laser head I thought I would investigate my speed so I will proceed as follows.

Reduce the Pulses/re from 2000 to 1000
Upgrade my Power supply to 48VDC
Reduce steps per from 400 to 200
Then I will carry out some accuracy tests at various speeds.

Maybe later I will upgrade my CNC4PC c11 Controller for a more advanced one.

Meanwhile many thanks.

George

Ok, all screws are 5mm pitch and directly driven from the steppers.
The steppers are wired 'Bi-Polar' parallel.
X axis is 2 phase 1.8deg per step. Rated voltage is 2.73 current 4.2A Resistance 0.65Ohm/phase and an  inductance of 3.2 mh/phase Hold torque 3Nm
Y axis is 2 phase 1.8 deg per step 1.93v 4.2 Amp 0.46 Ohm and 2.2 mH/phase Hold torque 2.0Nm

My supply voltage is only 30Volts, I guess I should double that!! ?
My steps per are set to 400, I guess I should halve that ?
My microstep drivers ar set to 2000 pulses per revolution.   
Physical movement of x & y axis shows 5mm movement per 1 360deg turn of the stepper.

also read somewhere that a stepper should by driven by 32 times it's rated voltage, is that correct ??

Thanks Craig.
I'm using pretty hi power 2Nm steppers on all axis (See pics) Drivers are MSd542 from Motion control products and my machine uses 10mm Ball screws (See pics)
So my thinking is the machine should be no slouch.
In the motor tuning my steps per are set to 400, this allows for a maximum speed of 3750mm/min (Cant go any higher ??)
My stepper drivers are set  to 1000 pulse/rev (can I set different than that)
What do I need to change to allow me to run my X & Y axis at 6000mm/min
It's a pretty robust construction as you can see from the pictures
I hope you dont mind me posting and asking these questions.

Thanks Craig, Velocity was set at 3000mm/min that's 118" per minute .
Why that speed, I dunno, I just saw a guy using 'Lightburn software' and he set initial bur speed of 100mm/sec. I thought it was pretty fast so I started to investigate the speed of my machine.

My axis settings are
400Steps, 3000mm/min. 575 Accell, 0.056g's
Does this look correct ?
