To start with, so you guys know what happened. We had a short circuit in the cnc about a month ago. The height caliper touched the back of the spindle control board in the front of the machine and it burned up pretty much every board in the machine and the spindle motor as well ! Syil was VERY good at sending replacement boards from china and we're also waiting on the spindle motor. We thought at the moment that this was all that happened. But this weekend, while working on the machine, something weird started happening.

If using fast travel / jog, the machine keeps going for like 1/2 an inch after we let go the the jog keys ! Also, when in cnc mode, miling is fine. But as soons as the head raises over the part to do some fast travel, it kinda bugs, stutters, makes noises, but eventually gets to where its supposed to go and keeps going.

We tried playing in mach 3 and nothing good came out of it. Reinstalled the software, un plugged everything, so on so forth, no change.

We think that the cnc controller box might be shot as well Crying right now.

I just wanted to inform the community and maybe get some ideas out there. Richard and the team at Syil are taking care of us and are quite frankly the best customer service experience we ever had. But if we can fix this faster, all the better for us !!!

Thanks,

David, I ran into a large number of loose electrical connections in my control box for my X2. Wires were barely hanging in place.

I believe that may have caused one of my drivers to go bad. Syil America replaced it promptly.

I tightened all my connections. You have to be careful doing this of course, with the power plug removed. Also, there may be capacitors in your machine that still dangerous after being powered off. There are none in mine unless they are buried in the power supply. Just don't go poking around without some idea of what you are doing.

The control box is extremely dumb. It only performs what the computer produces out of its printer port. If pulses stop coming from the port it is impossible for the machine to produce its own pulses. Therefore, any movement that occurs has to originate from the PC. If it keeps going for a short distance after you let the key off, then your acceleration is too low.

If your z-axis is missing steps, which it sounds like it is, it can only be caused by a few things. Your acceleration is too high or your gibs are too tight. Since the motor on the z-axis is capable of overcoming most pressure from the gibs, more than likely, you have your z-axis acceleration too high.

Are you using imperial numbers or metric in your motor tuning?

I'll have to check all that, I'm not sure what happens then. We didnt touch anything in the settings, at all.
Why would it start doing that all of a sudden ? Wouldn these settings have caused something before ?


The issues are with X and Y, not Z... at all
