Re: Long time problem is back

report_F045DA7F1D3D-1211181417_2023-01-25_14-10-53.zip I removed the wiring powering the VFD. Then combined all of the 115 V wiring into one and plugged it into another circuit in the building. Now air cutting the file that would not run yesterday. After running twice, 20:42 run time, X axis is rig...

Re: Long time problem is back

Where in the report is the error log? I am about to go out and un-wire the VFD then run the rest of the system on a different circuit in the building. I plan to air cut the last job that I ran and see what happens. I will also generate a report.

Re: Long time problem is back

We are in Titusville. Question, should the shielding for the VFD cable be grounded at one end or both ends? My wife pointed out yesterday that we never had a bit of problem till we moved into the building that we own. It is served by three phase power that has a wild leg. This was popular years ago ...

Long time problem is back

I converted my Shopbot Buddy in 2019. I used an Acorn board, Clearpath motors and cables along with Clearpath power supplies. Since 2021 I have had a problem where for no apparent reason the X or Z axis will stop moving although the computer is sending step and direction commands to it. Quite a few ...

Re: Random faults will a C86ACCP help?

Thanks Gary I think the light just went on and I will be following up on it. My machine has an E Chain that is at least ten feet long. The two Axes that have been deviling me (X an Z) run through that chain. So does the power cable for the spindle. So there is quite a load running through that E Cha...

Re: Random faults will a C86ACCP help?

Yes I did put in the resistors and also have done a pretty complete job of EFI proofinf.

One of the problems I have had involved a very large toolpath. Am I correct in guessing that Centroid loads the whole toolpath into RAM memory just before starting the cut?

Random faults will a C86ACCP help?

I have had my Acorn for over three years now. Since new it has has periods of intermittent faults and strange behaviors. It will run for months at a time just perfectly, then it will decide to loose steps and/or give an over torque fault and just stop moving. This usually starts when I slap a $60 pi...

Clearpath SDSK-3411D-RLN motors for sale

IMG_1220 2.jpg I have two of these motors. They were used in a conversion of a ShopBot router. They always worked perfectly and are in excellent condition. Slight tool marks on the face of one of them does not show when that are mounted and does not affect the operation. This was a hobby machine an...

Re: Z axis stalls out

After reading your posts I realized that a part of the Z track was impossible to clean without taking the whole thing apart. I have removed the Z axis from the machine and taken it apart. Wow, what a dirty mess! I have high hopes for this!

Re: Z axis stalls out

Gary The Tecknic manual talks about the 24 V supply and says that the motor will fault out below 18V. The very first things I did were to clean the rack and tracks and put fresh grease on. Another autotune is a good idea. I will do that. I put about a 3 pound weight on the axis last time I id it, wh...
