  1. Re: Avid CNC Plug and Play NEMA 23 - Y axis motors running in opposite directions

    Still no call back from Avid CNC. They were on top of it and called back within an hour when I wanted a $2500 quote, but now that I need help all I get is what sounds like a 90's answering machine.
  2. Avid CNC Plug and Play NEMA 23 - Y axis motors running in opposite directions

    I bought an AVID CNC(CNC Router Parts) plug and play NEMA 23 package for my DIY Ballscrew machine. Everything seems OK, except the Y axis motors are running in opposite directions? The Master is...

    To anyone still following this, it gets weirder. I spent a day with the machine down and just checking anything I could think of and many of the suggestions(thanks!). Nothing really seemed to be...
  4. Re: Cold weather affecting proximity sensors?

    Thanks guys, It was around 50 this morning and it was working fine. I think it's definitely the cold. It's only going to get colder though. Going to have to do something about it.
  5. Cold weather affecting proximity sensors?

    I built a 5' x 5' ball screw machine about 9 months ago and all has been working well, but the last few day when I first start it up I get sensor trip errors. I have to turn it on and off a few...

    Re: Dust Collection Requirements

    I have a 3HP DC in the shop now that is piped to all of my machines and it does a great job, but the CNC is way across the shop and ducting to it would be near impossible. So, I'm looking for...

    Dust Collection Requirements

    I have a DIY 5' x 5' CNC with 3HP spindle and I usually cut hardwood at around 180ipm and plywood at around 300ipm and I'm wondering if anyone knows what dust collection CFM this requires?

    I...

    Re: Bent X ball screw?

    Mystery solved! I removed the ball screw and nut and ran the nut up and down the screw and it didn't flow very well and then it just stuck where I couldn't move it at all. I suspect the balls were...

    Re: Bent X ball screw?

    It's not speed, It happens at very slow speeds and my other axes are fine and I've had them running at 400ipm with no issues. I plan on taking the motor and the ball screw off today and checking for...

    Re: Bent X ball screw?

    Thanks for the advice guys, as far as electrical, I have rewired everything. The X is wired exactly like everything else, and I have tried switch motors from the Y axis and it doesn't solve the...

    Re: Why did this happen?

    Thanks guys, I have a new collet on order, so I'm not going to run any 1/4" jobs this week until I get it, but I will run this same job again, just to see what happens.

    Re: Why did this happen?

    Ah, sorry I threw it away, didn't think to take pictures, but yes it broke right at the collet. In fact I had to push the part that was left out from the top because there was nothing left to grab...

    Re: Why did this happen?

    HA, I know that's not it, I had trouble with that when I first got my machine together. Also, this was about 45 minutes into the cut and after the bit broke I picked it up immediately and it wasn't...

    Re: Why did this happen?

    .25" bit. How would the collet cause, or contribute to the break. I was just so surprised by this, I would not expect a .25 bit to break in plywood at these speeds at all.

    Why did this happen?

    Re: cutting Acrylic with New Machine

    I was thinking the same thing and the only thing I can think is that I must have inadvertently had it in reverse on the VFD. There is a forward/reverse button and I must had hit it accidentally.

    Re: cutting Acrylic with New Machine

    As usual, the problem is me, not the machine. I had my spindle wired wrong and the bit was spinning CCW instead of CW. Once I changed that it's cutting like a champ. Just cut some maple at .25DOC...

    Re: cutting Acrylic with New Machine

    Thanks for the help. I'll go over it some more and try to find something. Any chance it could be my microstepping at 1/8?

    Re: cutting Acrylic with New Machine

    Yeah, I don't get it. I tried plywood today @ 100ipm 18000RPM brand new and sharp .25 2 flute cutter .25" DOC and it stalled? It's like the motors have no torque? Changed it to .125 DOC and it did...

    Re: cutting Acrylic with New Machine

    Yeah, that's what I thought too? It is stalling in the cut. Could the high RPM be melting the acrylic? The finish it's leaving is not great.
