Trajectory Assertion Error: E24-0505

[2A Finishing]

Ok, I was attempting to carve a project (.063 depth, 11"x8" carve area, .75" thick board) - I got a random "board may have been removed" error, but since the board had obviously not moved or shifted from where it was supposed to be, I hit "enter" to continue. The cutting chuck finished the pass it was on, and on the way back, the machine flipped out, moved the board laterally (x axis? - table rollers moved) and I got the error in the post title - Trajectory Assertion Error E24-0505

I've been suffering very minor tracking issues intermittently, and once in awhile (read, not every project) I get a "check tracking roller" or "front roller stuck" error but a quick application of 40psi air to clear any sawdust the dust collector misses and I'm usually back on track. This new error is one that results in not only an error that forces me to stop, but a cut that has destroyed a project.

Can anyone help with this? Search revealed nothing at all other than "call a nasa engineer"

Houston we have a problem!!

That is a new error code for me. Ruling out all board issues/problems for the tracking error I would look at/for bad or missing O ring on the brass roller, missing/slipped damper spring under the tracking sensor bracket, outfeed trays raised to high, rolled up sandpaper drive belts, rubber drive belts making contact with the brass roller, stripped X drive gears.

For constant compression roller errors/warning it could be time to remove/lower the roller to clean the dust out or check for switch adjustment and wire connections. I would also check for incorrect head pressure.

My guess is...99% of us aren't mechanical/electrical engineers.

Maybe head not level? (That error code is not in the list.)

Well, I will get on the checks and maintenance and hopefully I can figure it out between the information available here and a phone call to CW as soon as possible (probably not before next week between work schedule and the holiday).

The sawdust can cake up at the ends of the two compression rollers. It requires you remove the rollers and clean out the sawdust.

Look at these documents and see if that makes you feel more comfortable.

Email sent to LHR, looking forward to a response and instructions for shipping the machine in for diagnosis and repair. 97 hours on the usage odometer.

Sounds like a compression roller switch may be failing with an intermittent connection. Have you tried to blow out the sawdust in the switch(s) with compressed air?

I blow out the compression rollers before and after each carve I do - It doesn't seem to have much effect if any.

You may need to remove the keypad side panel and check the switches manually. Sometimes just blowing compressed air doesn't clean out the compressed sawdust good. The link in my previous post will tell you how. While you have the panel off check the switches for continuity with a multimeter. I cannot say if this is definitely your problem but it's a place to start.

EDIT: Also be careful using high pressure compressed air. 20-30 psi is more than enough. I just replaced a board sensor for the Veterans Admin. here in Tucson on a machine that had less than 10 hours on it because high pressure air blew sawdust up in the sensor.
