I've got a cnc lathe that doesn't want to work with the regular G84/G88 for tapping. Instead it requires G84.2/G88.2.

Does anyone know how to fix so that the postprocessor adds the ".2"?

anyone?

The problem is that i have always gotten the angle at the cut. i have always used a filter next to the pressure regulator on the back of the machine. Before i bought this jasic cut-70 i rented a...

I purchased an MPG2 from CNC4pc a while ago and i installed it using the guide on that site

The computer i am using is being used for other things as well so i have to bring it to the...

i was wrong regarding the nozzle before. it was a 1.3mm nozzle before and i replaced it with one of the same size and also the electrode without any difference. according to the seller it is for up...

The plasma machine is a Jasic CUT-70. i use the smaller nozzle and i think it's for up to 40 amp. the cutting distance is about 1 mm (0.04 inch)

i just got my machine up and running and i am working on tuning in the cutting data. right now i am cutting 3mm (0.12") mild steel and the best result i can get is with 40 amp, maybe 6 bar (87 PSI)...

That's a bummer. kind of annoying that shops like cnc4pc.com doesn't write that as a warning under the item description.

All this wasted time cost alot of money so now i cant afford a new card, so...

I tried some new things today. I connected the plasma machine to another outlet. That outlet is in another section of the power grid and is only connected to the same switchgear, maybe 150 meters...

Right now, both the USS and the breakout board is being powered from usb cables. Before i started to fiddle with everything both cards was powered with a small 5V 1A unit, smiliar to this. ...

I tried other ideas today with no go.

i grounded the smooth stepper card directly to the ground-connector in the 230volt wall outlet.
used a shorter usb cable and i removed the metal "cover" at...

anyone got any idea?

I have just upgraded my plasma machine from steppers to proper servos and a USB smooth stepper, which runs great until i start the plasma arc. sometimes mach3 stops immediately, sometimes it takes a...

ok. were do i find this utility?

the kernel speed is already set to max. and the math seems to add up. 3000*2000/60 = 100 000, if that is the correct way to calculate? anyway i tried to set the kernel speed to 25khz and the speed...

i just installed a new servo motor, a 400w leadshine with 2500 ppr encoder. the problem i am having is that i cant get any faster then 600 rpm. i have set the pulses per revolution to 2000 and i cant...

well i can set a slave axis for Z in the menu.

i am building something like the mori seiki NV6000 The NV6000 DCG offers the world's best accuracy - YouTube
i cant simplify it with 1 motor on...

how many axis motors can mach 3 control, if i have 2 paralell ports and 2 breakout boards? can it handle 2 motors for Y axis, 1 for X, 2 for Z and a 4th axis?

doesnt anyone have anything to say about my spindle idea?

Jason M:
Yeah i have kind of dropped the idea of that spindle from salecnc since there seems so be strong doubts whether or not it can cut steel without the drive dogs, and since i also want to be...

keebler303:
no i have never seen even a single picture of the spindle except for the ones from the webstores.

what spindle options have you looked into?


i had an ide. what if i took one of...

i talked to a salesman about it and he said it could be used for cutting steel, but salesmen are hard to trust.

i am planning a new project and i am thinking about using a SALE CNC Router Milling, CNC Laser, CNC plasma machine, China, Servo Motor Drive, UK, USA, Italy, Spain, Thailand spindle.

i am...

we have an old manual lathe that has been retrofitted with a complete heidenhain system. encoders, servos, software and so on. it is an old teach-in system, manual plus M. the retrofitting was done...

Mach3 reads the G04 code in milliseconds, but this can be changed in the settings menu.

so for a 2 second delay, you should write: "G04 P2000"
