General Mach Discussion / Re: Tool Change w/ Height Offset
« on: October 24, 2014, 12:57:16 AM »
You are correct that you need to use an "H" word after G43 so Mach 3 knows what TLO to apply to what tool. You want the G43 on the next line after the tool change command and of course H1 ,H2, H3, and so on applies to tool T1, T2, T3, and so on. Here is an example of how I was advised to write the code for tool changes when using TLO.
 
N1 G00 G17 G20 G40 G43 G80 G90
N2 T1 M06
N3 G43 H1
N4 T2 M06
N5 G43 H2
N6 T3 M06
N7 G43 H3

General Mach Discussion / Re: Step and Direction wire length

Hello John

Ideally what you want is a big metal box big enough to fit all your electronics in like your motor drivers and bob and power supply. That box is going to want to have a wire that runs to an earth ground. Your step and direction wires want to be as short as possible. The longer they are the bigger chance they will turn into an antenna and pick up electrical noise interference. That will make your motors do weird things like lose steps and change the direction of the motors. Having all your electronics in a metal box that is grounded will send any external electrical noise to ground and keep it away from your electronics. Some people install the computer inside of the control panel too. Personally I would rather have the computer a reasonable distance away and run the cables to the controller to reduce the chance picking up electrical noise. But ultimately it's your call how you do it. You can Google CNC electronic enclosures and then go to look at CNCCookbook website for some nice pictures of some enclosures and how they are wired.

Hello Chris

If you are using the on board 0 - 10 volt analog motor control on the C11 board for Spindle speed then then I would think all you would need to do is find the negative or ground wire and the positive wire on the hall sensor and run it to a negative input and the positive to one of your inputs on your C11 board and set that pin as the index in ports/pins inputs. As the magnet on the spindle goes by the hall sensor it produces an electrical voltage pulse which Mach 3 will use as you RPM tachometer and also to do the spindle speed averaging.  To be sure if you could do it that way you could email Arturo at CNC4 PC to be sure. I think that might work but I would be absolutely sure before you wired anything up. I think you hall sensor can't put out more than a 5 vdc signal for the C11 board.

Hello
 
I had the very same problem. Couldn't tune RPM to match what I wanted. Either tune low end and the higher RPM was way higher or tune higher RPM and lower wouldn't turn at all. Using a C6 board for the analog signal to a KBMM 225 DC speed controller.

I installed a C3 index pulse board from CNC4PC. http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=129. Then I went to ports and pins/spindle setup. Under motor control I have Use Spindle Motor Output and Step/Dir Motor clicked on. In special functions Use Spindle Feedback in Sync Modes, Closed Loop Spindle Control, and Spindle Speed Averaging are all clicked on. In Input Signals use the pin that the C3 board is connected to.

I now have Mach 3 RPM monitoring and when I command M3 S500 it's 500 RPM the same the higher RPM range. Also put a load on the spindle motor and the spindle motor will compensate for the load and maintain the requested RPM.

Any idea when the new release of M4 with the Darwin license bug fix will be realeased.

Hello Art

I installed new files and was able to get movement from all 3 axises. I was even able to run a circle pocket g code program. I tried to do some MDI commands to turn on my spindle and nothing worked. I looked in the error history and says Darwin license failed.

Hello Art

Well its not working for me. It will only allow 1 axis to work. If I have more than 1 axis enabled in Darwin I can't get Mach 4 to enable and I get a Darwin Buffer Error - motion out of bounds. Its like Darwin isn't licensed. Darwin.dat and Mach4.dat are in the license folder. I have uninstalled and installed Mach 4 and Darwin several times and reconfigured and still have the same results. Restarting Mach 4 has no effect nor does rebooting computer. Mach 4 is showing it's licensed. It would be nice if there was some way to know if Darwin was licensed or not. Starting to get frustrated.

Hello Art

Since Mach 4 2038 is up on the website. Will Darwin 2030 work with this release or do i need to wait for Darwin 2030 to be updated to 2038.

I would like to see a limits overide button like in Mach 3. When I land on my limits I can't jog off without deactivating them in Mach 4.

Hi Art

Darwin 1.145 fixed the Darwin regs forgetfulness bug. I shutdown and restarted M4 several times and settings stay the same. I changed spindfreqhi to 800 for my step/dir spindle and it stayed rock solid thru all the shutdowns and startups. Thank you

Eric
