Now that's what I call a recommendation.

General Mach Discussion / Re: Selecting the right equipment for a Bridgeport BOSS retrofit

« on: December 15, 2015, 01:54:35 AM »

If (at this moment in time) you just want the basic X - Y - Z milling then I would go for Mach4.
If you want the X - Y - Z and to incorporate all the air controlled functions (at this moment in time) then I would go for Mach3.

(Mach4 is coming along slowly but, in my opinion, it is not yet ready to fully take over from Mach3)

From the official documentation...

Software Requirements

Mach4 Recommended Requirements:

PREFERRED: 32 or 64-bit Laptop or Desktop – Using an External Motion Controller
•   Windows XP, Windows Vista, Windows 7, and Windows 8
•   An appropriate external motion controller
•   Mach4 Plugin for the selected Motion Controller
•   2Ghz CPU
•   1GB RAM
•   Video Card with 256MB RAM(Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)
*Use of Parallel Port for machine control only with desktop style computers with 32-bit versions of windows 7 and below.
32-bit Desktop – Parallel Port Recommended Requirements
•   32-bit version of Windows XP, Windows Vista, or Windows 7
•   Mach4 Parallel Port Legacy Plugin (cost applicable)
•   2Ghz CPU
•   1GB RAM
•   Non-integrated Video Card with 256MB RAM(Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)



Mach3 Minimum Recommended Requirements:

Requirements if using the parallel port for machine control:
•   Desktop PC (Laptops are not supported) with at least one parallel port
•   32-bit version of Windows 2000, Windows XP, Windows Vista, or Windows 7 (64-bit versions will not work)
•   1Ghz CPU
•   512MB RAM
•   Non-integrated Video Card with 32MB RAM(Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)
Requirements if using an external motion device for machine control:
•   An appropriate external motion controller (options can be found on the Plugins page)
•   Desktop or Laptop with Windows 2000, Windows XP, Windows Vista, Windows 7, or Windows 8
•   1Ghz CPU
•   512MB RAM
•   Video Card with 32MB RAM(Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)

Sounds like you are well on your way Jeff. Lots to learn but it's all justified by the result.

Assuming I understand your requirements - If you have created an on screen button then pasting in this script will enable Output7 to be activated / deactivated with alternate button presses. In your screen designer add the led and link it to output#7.

If IsOutputActive(OUTPUT7) Then    ‘Check to see if its on
DeActivateSignal(OUTPUT7)                 ‘Its on so turn it off
Else
ActivateSignal(OUTPUT7)               ‘Its off so turn it on
End If

General Mach Discussion / Re: Mach 3 or 4 with PMDX 126 & ESS

« on: December 14, 2015, 10:37:13 AM »

Does anyone know if I purchase Mach 3 and pay a little extra later on and move over to Mach 4?

Steve

Currently, there is no option for a Mach4 discount purchase price to existing Mach3 license holders (there is no upgrade at a discount price offered).

Hi Richard,

Sorry, I know I've asked a lot here. Thanks to anyone that helps. Tweakie and RICH have been great to me, but I don't want to look a gift horse in the mouth.

No fear of doing that my friend - ask as many questions as you need. 

From your calculations it would appear that your stepper driver is set to 1/8th microstepping.

I don't know the exact figure (I am sure that someone here does) but Mach3 supports a precision which is many times greater than the accuracy of any of our machines so you just need to resolve this Z axis steps issue you are experiencing. I think we have mentioned it before but you have thoroughly checked all the mechanicals for loose grub screws, slipping coupler, etc., etc. ??

Excellent work, very neat indeed.

CS-Lab / Re: CSMIO/IP-A plugin with win10 ok?

« on: December 13, 2015, 02:21:59 AM »

The best cure for this is to remove update KB3035583 and then untick the 'Give me recommended updates' under change settings.  No more nagging until Microsoft force everybody onto there latest pay as you go scheme.

Perhaps not all versions of Win10 are the same.
Removing an update does work but I wonder how long it will be before Microsoft puts it back ?
I can defer updates but as Microsoft says it makes little overall difference.

"Some Windows 10 editions let you defer upgrades to your PC. When you defer upgrades, new Windows features won’t be downloaded or installed for several months. Deferring upgrades doesn’t affect security updates. Note that deferring upgrades will prevent you from getting the latest Windows features as soon as they’re available".

General Mach Discussion / Re: Z-Axis Not Always Positioned Correctly

« on: December 13, 2015, 01:38:38 AM »

Do you think reducing the microstepping on the Z Axis driver so it takes less pulses to move 1" will have any impact on the results?

It should not make any difference unless you PC is just not up to the task.

The pulse width is set to 5us for step/dir on all axis. The TI driver has a minimum pulse width of 1.9us so this should be OK, right?

Try some experimentation here to get the smoothest motor motion (2uS gives me the best performance).

I was running the driver test and checking all frequencies. Even up to 100kHz it reports the system is OK. I noticed that up to 65kHz the CPU usage is less than 5% but 100kHz is ~50% but I don't see any reason to push it that high. When I look at Max Variation I see mostly repeatable spikes and values of 15us or 23us. This doesn't seem to change when I change the frequency but occasionally I see nice smooth line aith maybe variations of 5-8us. Is ~20us variation something to worry about? Should I break out the scope and see what the step pulses actually look like?

Unless you definitely need a higher kernel speed (to achieve the desired rapids) then use 25kHz.

I think it's almost impossible to guess at what you may have done so perhaps the best solution is the reload the screen .set file (standard screen is 1024.set).

If you don't want to re-install Mach3 then - If you have a spare PC install Mach3 on that, then copy the 1024.set (or whatever screen set you are using) file and transfer it to your machine PC. (Please be aware that your scripts for any added buttons are stored in the screen set file).
