The transmitters can be set either way to match up with the speed controller. I have never seen a standard published so you should probabbly design for either. Some do not have reverse and use the

Hi everyone, I was hoping to pick someones brain on this. I have two 3 axis motor controllers, one is made up of IMS IM483's and the other OEM 650's. The IMS is using a 40vdc power supply and the

Wayne, I'm sure you are correct. From memory, it is also how they set the off position as well. Cheers, Peter. Wayne Weedon wrote:

Hi, I just reinstalled Windows XP in the normal way, so with ACPI. Now Mach 3 is running ;-) It is not as smooth yet as i want but i didn't use the optimisation-file yet. Happy that is working again!

Hi Manu, I've had a look and I'm fairly sure that I can get the DigiSpeed-XL produce an RC signal that should work fine. I can add it as a mode selected by the mode jumpers. I have a question.

May not be the processor - could be the chipset, especially if it uses the same Via chipset as in some models of Shuttle. Some work, some just don't :( Steve Blackmore --

Hi Lester Have you checked the parallel port output voltage? A lot of laptops and modern desktops now seem to put out only 3.8V instead of the 5V your driver board probably needs. Cheers Dave wrote:

Hi Art, My setup : Kernel: 25,000Hz Spindle Base Freq: 50Hz Min, - Max Pully ration: 1 to 10,000 After scope measurements I get this ! If I set the scope resolution to 2ms/div I do get the correct

Right guys ( and galls? ) Spent some time yesterday playing with a TaigCNC machine and comparing Mach3 with the DOS package that normally drives it. The original control program is running on an old

Yes, that and a HT model. Also its not good idea to disable ACPI or anything unless you really HAVE to. The "optimisation" file should have a disclaimer saying "only do this as a last resort". Steve

Your (current) number should be based on the highest target speed (in IPM) calculated to how many pulses per second it takes to do that. It's a function of the "gearing" and the line count of the

I think the Phoenix type controllers are already opto isolated, but I am not sure. According to the advice given by a member on CNC-Toolkit rigging a Servo Tester to provide a pulse should allow speed
