Mach2 to Mach3
« on: November 25, 2006, 09:40:16 PM »
Hello Everyone: :

I am very new to CNC controls, but I am very excited to learn.
I have purchased a router that has Mach2 installed and I have purchased a license for Mach3 with the Newfangled Solutions bundle, I have tried to go step by step while watching the instillation video but the motors do not move. I think I am missing something basic.
Any help will be greatly appreciated
Also the machine is set up in metric and I would like to change it to inches during the setup, In mach2 the steps per unit is 110.5 and the acceleration and velocity is set at 160 units/sec.
The router seems to work fine with Mach2 except the spindle does not always start up at the beginning or shut down at the end of a program and I don’t know what g-code it is looking for to start and stop. The spindle is controlled by a delta vdf from a serial port. When I try to turn off the spindle with the toggle in mach2 the program usually locks up and I have to shut it down and restart.

Thanks

Chuck

Can you post your xml file for Mach2 and Mach3, it will let us see what ports and pins you are using. The xml files will be found in your Mach2 and 3 folders and will probably be the Mach2mill.xml and Mach3mill.xml.  To attach them go to the full reply form and you will see at the lower left "additional options" click that then just browse to the location of your xml by clicking the choose button.

Thanks for looking at this for me.
I have attached the XML files and the machine manual

I am just leaving for work but I will have a look when I get home this evening if no one else has sorted you out by then.

 Not long in from work and its getting late (11pm). I tried to use your profiles(both Mach2 and 3) and I get total computer lockup in Mach2 as soon as I start to look at config, in Mach3 I get program lockup. I will have to look at the XML files themselves to see if I can find anything but afraid my eyes are too tired to look at the moment. It will be tomorrow evening before I get a chance, sorry.

Sorry for the delay in answering I have been out of town this week.
Mach2 works but I cannot get Mach3 to enable or move any axis.
The computer I purchased to run the machine did not come with a parallel or serial port so they were added later, as a result the address is not what a factory installed port address would be and you will have to change it to your address is to run them,
Can you use the manual to set up an xml file for Mach3.

Thanks for all your help

 As I am just using it on a computer NOT hooked up to a machine I should be able to load your xml whatever the port address is, I just dont understand why its crashing. I will go into the xml and change the address just in case it is looking at something else on my computer and not liking it.
 The easiest way to set up Mach3 from Mach2 settings is to open Mach2 and look at all your ports and pins, motor tuning etc and write them down. Close Mach2 and open Mach3 and eneter all of these figures, slow process but well worth it ;)

I have corrected some wrong pin settings and the axis seem to be moving correctly.
But I cannot get the spindle to run. I have the comport set but Mach3 doesn't talk to the VDF.
Also the VDF is set so that 400 Hz = 24000 rpm, will Mach3 convert spindle speed comands to a matching Hz output.

Thanks

afraid I have never used Mach to control the spindle through a VFD. I know there are guys here that have done it so they may be able to help. Do you have a board that interfaces the VFD and Mach?
