I am new to Mach3 and CNC machining and recognize that there is a learning curve.
I have a DIY CNC that is NOT using the spindle control and everything is working fine. I am now adding a diode...
I am new to PWM control and need some help. I have a DIY CNC router that DOES NOT use spindle control and I am adding a 6W diode laser.I have followed many of the online youtube videos on setting...
So it is not running as well as I thought. Can only reliably get about 60 ipm. With the 5mm screws, that is about 300 rpm on the motor. If I run it any faster, the motor will stall part way through...
Did a lot of playing with the microsteps, kernel speed, acceleration rates and velocity and have it running reliably at 150 in/min. I think this is about the best I can hope for with the 5mm screws....
Been looking for a NEMA 34 stepper and most seem to be 8 wire. What are the advantages and disadvantages of Bipolar Series and Bipolar Parallel? If I connect it in series, my existing driver should...
So I have the 48 volt supply installed. Increasing the microsteps to 1/8th helped a bit. The 48 volt supply also helped but it is still not running as well as I need. I had another look at the...
I have a 48 volt 10 amp power supply on order. I will see what that does.
I currently have the acceleration set at 10 in/sec/sec. Don't know if that is too high or too low or somewhere in a normal range
I am new to all of this so I am trying to find my way. What would be a recommended setting for acceleration?
Could the power supply be too small. It is rated at 9.7 amps. All three drives are driving the same motors. The drive specs say <4 amps. However, this power supply seems to be common for complete...
Sorry. Some info I provided is incorrect. The power supply is 36 volts but the drives are only 5 v pulses. The motors are rated for 6.3 volts
The distance between the linear bearings is fairly large. I designed it that way so that I would not get twisting as the gantry moved. The motor is a Nema 23 425oz motor. Power supply is 36 volts....
Built my DIY CNC over last winter and am now starting to get into doing some machining. The problem I am having is that the stepper that moves the gantry is stalling. When this happens, the spindle...
Ok! everything is workings properly.Motors are moving, everything going in the right direction. About to wire the limit switches before installing the table and setting up the motors and screws. Have...
I think I have figured it out. The OS is using the correct port, but the card is using a different port and it cannot be changed. But there is good news. My motherboard has built in parallel port...
So I need to verify or eliminate the breakout board as the problems. All the breakout board does is take the signal from the parallel port and put it through optical isolation. In theory, the system...
I agree, but the bigger problem is that the pins on the parallel port card should behave the same as the outputs on the breakout board. The only difference is the optical isolation. I have measured...
Yes - 32 bit windows 7. I assume it is a 5 volt card because when I measure the voltage directly at the parallel port on the card I get 4.6 volts
Sorry, I meant 0x378. I checked the device manager and I get 2 parallel ports showing. The ECP printer port is set to LPT1 and is using I/O range of 0378 to 037F. The
PCI printer port is on LPT3...
Checked that port 1 is 1x378. Set the pins for step and direction in Mach3 and made sure they were on port 1. I have one motor connected and when I energize everything, I hear the motor power up. I...
Thanks for the info. Unfortunately the price on the 1605's was just too good to pass up.
I now have another problem. The build is going fine and I am now wiring and testing the electronics. I...
I am about to start my DIY CNC router. Have looked at at a lot of DIY builds and have designed my own based on features from several other builds. I will be using 1605 Ball screws and round, fully...
