General Mach Discussion / Re: Win7 and the parallel port
« on: September 05, 2018, 10:37:37 AM »

A recent Windows 7 security update has affected those who use Mach3 and Mach4 with a parallel port connection. Basically, when the parallel port is used to control your machine it "takes over" the operating system and the new update does not like it, so it crashes the whole system. The following is a fix that does not require you to uninstall any updates or upgrade to an external motion controller. These are still valid options, but this is quick, easy, and should have you back up and running in no time. Here are the instructions, which I'll break down for you below:


Go into command prompt with administrator rights and paste and add the below registers.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

Restart the computer for the changes to take effect.

(You do not have to change MinVmVersionForCpuBasedMitigations.)



You can follow along with these instructions at our support video here: https://youtu.be/C_O6TQhgMlA

1.) Go to your start menu and start typing 'cmd'. The command prompt (or cmd) option should appear right away. Right click and select 'Run as Administrator.' You need to be using an administrator account as well.

2.) Once you've opened the command prompt and see 'Administrator' along the top, you're almost there. Copy the first line that starts with 'reg add'. Right click in the command window and select 'Paste'. Then hit your 'enter' key.

3.) Repeat the previous step with the second line of code: copy and then paste into the command prompt window on the next line. Hit 'enter'.

4.) You should received a successful message after each line. If you see an error message regarding your access being denied, you should double check that you are logged in to an account with administrative privileges and that you are running the command prompt as an administrator (see step 1).

5.) Restart your computer.

6.) Open Mach3 and get to work.

7.) Happy CNCing!

Thank you to MachMotion for sharing this fix with us.

Let's try something new then. Open up the Script Editor, go into the Wizards folder, and find mcCvTuningWizard.mcs. Open that and find the UI information (starts around line 132). You can change the values in wx.wxSize ( , ) to make the wizard window larger. You may also need to change the wx.wxSize( , ) in the line below as well. Give that a try and let me know if it allows you to see and use the buttons at the bottom.

Thank you,

What is your scaling set to? I had another user in the past with this issue (Win10 computer) and they had to adjust their scaling in order to see the entire wizard window. You can search 'scaling' or look in the Display settings.


Good morning,

This has to do with your settings in Windows. You may need to play around a bit with your resolution/scaling settings. If you are using scaling to "zoom in" that can cause part of the wizard window to be cut off, as you're seeing.


Mach4 General Discussion / Re: Toolpath not showing on custom profile

Hello Oscar,

Is your machine homed and zeroed before you load the g code file? Have you tried regenerating the toolpath? Have you tried zooming in or out in the toolpath window? If the g code is loading, a toolpath should be generating. I'm wondering if it is just "out of sight".


Newfangled Mill Wizard / Re: So a PC failed
« on: August 06, 2018, 09:40:59 AM »
So if your PC that running mill wizard fails, you must buy a new license even though existing license is no longer in use?

That is completely untrue. If you've purchased your license in the last few years, you can log in to your account at machsupport.com and go to 'Manage my Licenses' to enter in the new PC ID shown in the Help>About menu in Mill Wizard--once you've installed it on your new computer. This will generate a new license and send out an email with a link to download the file. If you bought your license more than 2 or 3 years ago, you are most likely in our old system, but we can still get you a license for your new computer. If you submit a ticket at support.machsupport.com that includes enough information to locate your purchase (email, approximate date of purchase, name on license) and your new PC ID, we can dig you up in the old system and get you taken care of.

I sent out a response to your ticket, but I wanted to share the solution here in case others have this same issue. When OP lost power, Mach4 had to close unexpectedly. This can cause some funky things to happen to your profile. What happened here is that the Operation Lock setting was turned on in his Machine.ini file. The fix was to open up the Machine.ini file and change OpLock=1 (on) to OpLock=0 (off).

Mach4 General Discussion / Re: Mach4 demo will not load

Hello Mike,

There was a Windows 10 issue with Mach3, but that was corrected when a new patch was created and included in that installer. I have not heard of any other issues with Mach4 and Windows 10. If you'd like to send in a quick ticket at support.machsupport.com one of our techs can remote connect to your computer and try to diagnose what's going on.

Thank you,
