PoKeys / About threading and noise problem for Pokey 57CNC

« on: September 12, 2017, 12:11:43 PM »

Dear Sir
I have plan to change my mach3 parallel port control cnc lathe with Pokey 57CNC controller. I have some questions about this pokey controller.

First one is threading function. My old  parallel port control is using index pulse signal for threading and spindle feedback. Is the pokey controller support this function with Mach3 software (Not Mach4)?

Second one is Noise problem. There are a lot of noise effect to the controller and computer when the machine is running (especially Spindle VFD running). Is the pokey controller include noise filter for IO port?

Thanks..

General Mach Discussion / My machine stop while running a program

« on: September 22, 2016, 02:00:41 AM »

I have some problem with my mach3 control lathe machine. My machine stop while running a program. The reset button is blinking but the cycle start led is still on. In my knowledge, the cycle start led will stop when the reset button is blinking. But sometimes, my program finished and some time this same program have occur this problem. My software version is Version R3.042.056. There are 2 parallel ports in my control system. Please give me some advice what should I do to solve this problem.
Thanks..

General Mach Discussion / Port2 Pin 2-9 cannot use as input signals

« on: January 15, 2015, 03:24:40 AM »

Dear Sir

I have some problem about parallel port 2 address configure. I want to use Hand wheel input pin for Port 2 Pin (2-9). But these (2-9) pins cannot use perfectly as input signal. My problem is as follow..

My port 2 address is 'c010' and the software cannot recognize the pin (2-9) as input. So I change the port 2 address to 'c000' and test again. There are the same problem. So I change the port2 address to 'c010' again and test again. This time the port2 pins (2-9) are working as input and the handwheel can work well. But I restart my mach3 computer and test again with handwheel. I face the same problem. If I change port2 address two times (change c000 and then c010), the problem is ok.

So I need to change port2 address two times when I always start my machine. How can I solve this problem. Please give some advice for this problem. Thank a lot..

dspMC/IP Motion Controller / dspMC/IP Motion Controller with index pulse for spindle feedback

« on: April 10, 2013, 01:14:54 AM »

Hello Sir..
I have two machine with your controller. One machine use an rotary encoder for spindle feedback and this machine is running well now. But I have no encoder for next machine and I try to use index pulse circuit for spindle feedback. So I connect index pulse signal in one of the input pin in your controller and I set index input signal in mach3 input setting. But this system isn't work. So, I want to know can I use Index signal for Spindle feedback with your controller? Please give me some advice.. Thank Sir..

General Mach Discussion / FRO % zero setting for brain

« on: March 28, 2013, 10:23:29 AM »

Hello Sir..
I am using digital feed rate rotary switch to control the feed rate of my CNC.. I use 4 input pins from parallel port for this switch and I wrote some brain for controlling feedrate. But I can't write the brain for feed rate % to zero in my brain.. I want to use feedrate zero setting in my machine because I want to stop my axis sometimes using with feedrate switch in zero position.. How can I do for this setting.. Please hep me.. Thank so much..

General Mach Discussion / step feed rate in jog mode

« on: September 28, 2010, 10:17:36 AM »

Dear Sir

Mach3 has 'step' and 'continuous' in jog mode. Continuous jog speed can control with job slow rate setting. How can I control 'step' jog speed? The feed rate for step job is 6 mm per minute. It is very slow for me. I want to change the feed rate in step mode while jogging. How can I change? Please help me...

Best regards,

General Mach Discussion / Computer hanging with Mach3

« on: March 08, 2010, 10:31:41 AM »

Dear Sir

My computer often hangs when I use with Mach3 CNC controller. My computer specification are:

Processor - Pentium 4 2.66 GHz
Memory - DDR 512 MB (333)
HDD - 80GB
Graphic - MX400 (64 MB)

My machine is 3 axis Milling. I use 60kHz kernal speed. I decrease kernal speed to 45kHz, but I face the same problem. There is no spindle speed control (only relays on/off). What should I do? Do I need to change my PC? I hope someone can give me some advice.

Best Regards,

Share Your GCode / NC file for 4 axes machine

« on: March 02, 2010, 08:04:42 AM »

Dear Bro

I want to know which CAM software can generate 4 axes tool path for Mach3. I use Master CAM 9 for 3 axes machining. Can I use Master CAM for 4 axes maching?  Now I try to improve 4th axis rotary table in my Milling machine. So, I want to know the 4axes tool path with rotary table (A) axis.

I also want to get 4 axes tool path NC files that someone did. I hope somebody advice me.

Best regards,

General Mach Discussion / home switch and limit switch problem

« on: February 03, 2010, 08:05:13 AM »

Dear Bro

I have some problem with home switch and limit switch. My mach3 cnc machine uses one home switch and two limit switches for each axis. Mach3 cnc software cannot sense limit switch while reference home. I want to use limit switch while reference home. How can I change setting for this problem. Please help me. Thank a lot.....
