Hi, A unipolar motor rated at 1.63A can be run at 2.3A bipolar parallel. This would be preferred over the series winding. This would be a Vref of about 3.3V ...
Jeff, I bought XS-3525 driver kit along with the 3 motors and the power supply. The pacsci motor came with the hardware I used to make the x axis. I was...
I have done a search but can't find what setting for the Vref for the 497 oz motors. I will be running a fan on the Xylotex 3 axis board. thanks, Rod...
Hello All Members, I have a question of my board(4 axis). The Led don't light up when I connect power supply. What is problem? I check Amp and Volt of my power...
Hi, The vref can be set anywhere up to 3.60V. You will get more torque by using a higher Vref (not to xceed 3.60V). But at higher speeds you may also see...
Hello, I have questions of power supply.I have read that 5 Amp is enough for xylotex 4 axis board but more than 5 amp is better. Is it right? If so, I want to...
Hi all I can say I'm expert in making 3D modals using cad software's but not that much in running them on CNC I use Roland MDX-20 but now I'm trying to use...
Hello, I have other questions of this LED problem. Acutually I am reading and studying about this problem now, but I can't figure out what the problem is. My...
Hi all i am a newbie here and just purchased a Deepgroove 4 axis Taig mill on ebay 400oz steppers i think you will have all seen this on ebay anyways my...
Hi, More amperage will not hurt the drive but, but it will not necessarily produce any more power from the motors. In many cases a 4.3A supply will be fine as...
First off let me say if there is a post here that answers my question please link it to me I could not find a definite answer to my problem. thank you... I am...
Hi, The Xylotex steptest program will not work under WinXP/2K. It requires DOS capabilites that the newer windows do not have (allow). The program should...
Hi, The drive board generate its own +5V when you attach the VBB/GND wires (typ. 24VDC) and then power up the power supply. You do not need to apply +5V to...
Hi, It certainly sounds like you are experiencing resonance stalling. If you are running at 24VDC with a switching supply, try adjust the supply up to 27VDC....
I notice when I first setup my y axis, that grease helped alot... The power supply that came with the 3 axis kit is set to 27VDC I made sure of that when I...
Hi I have this same problem. Y and Z, X ok. I have tried everything and the only way I could fix it was to run Y and Z at 1/2 step. Didn't try 1/4 step. ... ...
Hi, You may (or may not) be able to "tune" the problem away. I know that some people have gone quite low in the Vref setting (down below 3.0V with the similar...
I think it is a vref issue cause the motor stalls off of the cnc as well. I am also going to try putting it in 1/4 step mode to see if I can't get the...
Justin, I'm new to this so don't take my word for it but it sounds too me like you have your steps per rev. to high for your motors. Are you running mach 3? If...
... Humm, says Gene, breaking into a thread he didn't start. In that case Jeff, can you comment on the attached pix of the couplings I made for this micromill?...
... Gahh, the server stripped it. Sorry for the noise folks. ... -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury,...
Hi Gene, Yahoo doesn't allow attachments (at least that is the way the group is setup). Can you download the pictures to the FILES or PHOTOS section? Thanks, ...
... When I next think about it, I will post them to pastebin & mail the link to the list. I won't have time now till the middle of next week due to a trip to...
My y and z axis are working fine now. I just got two jumpers and put y and z on 1/4 step mode and reset my steps per rev in mach 3. The worst vibration is in...
I have a couple of questions and sure someone on here will know the answers. For Xylotex board, DB25 Port Cable Pin # 2 tells x to move and Pin #3 tells X to...
I had to go up to 1/2 step mode. While doing a test cut my y axis stalled around 22.8 ipm now it is the worst at 1.5 ipm but not so bad it stalls. I decided to...
Hi, Pin 3 is the DIR line. Low (0V) makes the motor turn one direction, high (+5V) the opposite direction. Pin 2 is the STEP pin. For each rising edge (0 to...
