I cant get the M3 M4 or M5 commands to work, The controller's spindle on/off is hard wired to port pin 1, and the PWM is wired to port pin 17. In the config settings/ports and pins/output signals, there are two entries one for Enable 1 and one for output #1, by changing enable 1's active low i can physically turn the spindle on and off, but the spindle cant be turned on or off through M3 or M5. M4 CCW has same settings as M3 since the milling spindle needs to spin clock wise.
DeskCNC will accept DXF file format for its foam cutter operation. Since the machine is a true 4 axis machine – it can cut one shape on the left side of the machine and a different shape on the right side. The Axis ratios are used in the DeskCNC machine setup. In the case of the IMService servo drivers with Globe motors, the belt reduction is setup so that one revolution of the output shaft is about 2.8 revolutions of the motor shaft.
Does any one know how to set this up exactly. Ahh, bullsh!t.somewhere the Mach 3 settings you've done are set up wrong.go back to the config menu and set it up again as if it's a new machine on Mach 3.if you still get a wrong response your controller probably is faulty. Have you tried writing a simple G code program with those M commands.in the correct format sequence.some people write sloppy code sequences and wonder why they get problems.
Running a simple G code program will get Mach3 to trouble shoot the point where you've made a mistake in your coding.ask me how I know.I'm still learning from the bottom. If Mach 3 is a problem for you.you are the problem.

Include the probe setup even though one was supplied. Nor did it have any spindle control setup because the controller had a manual on/off spindle switch and speed control, probably because a link cable was not fitted between the JP-382A axis control board and the JP 1482 spindle board, which I've now made.YES I've written a simple G-code to test it though it's not needed as you are aware you can run commands from the MDI screen in mach3.
Re your last comment in your message, yes i have a problem matching Mach3 settings to the hardware i dont have enough information about the settings which is why i asked for help. PS I now have got the motor to switch on an off with the M3 and M5 commands, but now need know how to set Mach3 to control the spindle speed with M3 Sxxxx, I dont have a pulley wheel on my 48volt dc motor and no idea yet on what base frq to use. Hi, if you got Mach 3 with the machine you probably have a corrupted version as that is the opinion of most here. I would down load from the Artsoft website the.062 version of Mach 3 as it's better than the later versions.or so I'm told. ALSO.I would dedicate a computer just to run Mach 3 and nothing else, not even MS Office and especially not with an internet connection as you won't be running any anti virus software.an anti virus program could detect that your copy of Mach 3 is corrupt and do funny things.whatever. The point is, if your copy of Mach 3 is bad, all programs you load will also go bad at some point.for no apparent reason.
Ian don't be a dick. Snakips If you have a look on the Mach3 website here goto here and grab the Mach3 Manual it's the first one you wont.
Then goto the software and downloads tab in the drop down go down to downloads and updates click on Main then click on where it says FTP Downloads then click on FTP server main menu then click on mach3, you wont Mach3 version 3.043.062 Now to see if the copy of Mach3 is a pirate version in the top Left corner what does it say beside the Mach3 symbol To find what connections to use on you controller have a search through here and the mach3 forum and google most people with that controller run into the same problem no manual, the info you need is out there. In the config settings/ports and pins/output signals, there are two entries one for Enable 1 and one for output #1, by changing enable 1's active low i can physically turn the spindle on and off, but the spindle cant be turned on or off through M3 or M5. M4 CCW has same settings as M3 since the milling spindle needs to spin clock wise.
Does any one know how to set this up exactly. In ports and pins, spindle tab, do you have disable spindle relays Unchecked, and output 1 assigned to M3?
Are you seeing the spindle on LED light up when you do an M3? You need to see if the enable signal is changing state with M3/M5. I'm not sure if I've seen anyone use an enable signal with a spindle. Hi Ian, The machine is a ChinaCNC 3040, with a Z-DQ 4 axis controller, though the machine is not fitted with the 4th axis. There is a history with the JP 1438 speed control board which CinaCNC use in there controllers, they are supplied without the link lead between the JP382 board and the JP 1438, so software control is not possible, not sure if the missing lead is deliberate due to a design or software fault in the speed control board., there is a manual spindle on/off switch which switches the software opto's input. The STC micro under the board has the speed control 5K pot on pin 15, which is a ADC pin, The ext PWM is feed thro a low pass filter to pin 16 which is also a ADC pin, there is no other signal going to it to indicate software control or hardware control. So I'm guessing it needs to read the voltage on those two pins to enable one or the other to control the spindle speed.
From my point of view it seems a bit daft to have an external PWM in filter it down to DC only to regenerate it for the FET driver stage. Simple solution would be to use a 5v change over relay switched on by the software spindle on/off opto and connect the common pin to the Fet driver stage, with the normally closed pin to the micro output, and the normally open to the external PWM i/p. The when software switches the spindle on it automatically connects the PWM signal direct to the Driver stage.
