Spirit Laser Y motor Malfunction

[Stanley Waldrup]

Hello All, I have a Spirit 30w Laser and it will not get past the Initialization. It comes up with a Y-Motor malfunction. I swapped the Y and X motors and the problem did not follow so its not a motor. All the power supply voltages are right on and I checked out the cables with an OHM meter. no problems found there. Any Ideas other then a main System Board? Thanks Stanley

Sorry, that happened to me a couple of months back and it was the main system board.

There is a little tab that breaks the optical connection to tell the machine its reached the Y limit at the top of the table when it boots , have a look to see if its not broken off or that it is indeed breaking the optical beam , its by the small pcb , at the right end of the gantry, a protruding tab . Even if its not broken , tape a small piece of insulation tape at the end to extend its reach into the U shaped optical switch and try again , we have had this happen to us a few times.

Hi. It happened to me to 2 years ago. My problem was on mainboard. Fortunately, I replace the 3 "integrated" on mainboard (inexpensive!), those that have heat sink, and the mainboard works again. Good Luck!

Edu, Can you tell me more about this. Do you have any part numbers or a supplier? Thanks Stanley

[Stanley Waldrup]

I'm afraid of that!

Tried it Rodney. All the tabs were in place and tried the tape trick with no luck...

Hi again. Here it is a foto of the mainboard.

Marked in red the pices I changed. I didn't it by myself. A guy from an electronic shop did it.

Must have to take a part the 3 heatsinks (it has screws), then desoldering the three integrated pieces (like a chip with spider legs ;) ) and then resoldering the new ones.

The integrated pieces have a number printed.. is the reference to find it on a electronic shops.

..After a year and a half the mainboard fails again.. but this time was a diferent error and replacing this pieces takes no effect. I hope it works for you.

Good luck again Stanley!

Pd: The pieces cost was about $5 each one :-D

I think it is the L6203 DMOS full bridge driver.

We tried a repair on an old board using this , but there was something else wrong.

Thanks Rodne, I will give it a try and let you all know. Stanley

I had similar problem 14 days ago with X axis ... and problem was in small board mounted near servo... price about 50 USD. It came when i engrave and after switch off and on machine didnt start .... error was on display during initialization .... Martin

Was it the Board toward the front of the machine or the one that travels with the X-axis Carrage?
