SX3 XMT control board PIC clone

[Jan Rune]

Hi,
Im in the progress of making a new contol board for the Siex SX3 BLDC motor. My main goal is to have full spindle control via Mach3. Im also liked NeilW20 idea on manual override of the spindle speed. So that is something i have to integrate. If there are anyone else with any good ideas. Please tell, because this is going to be free for everyone(thats HEX code, Schematics and PCB files.)

I have used this weekend to familiarize myself with the XMT_Driver_1000(Version B0) board and XMT_Control_1000&1500(Version B0). The XMT_Driver_1000 board is gonna get used as is without any modifications.

This thread is not looking very interesting right now, but in the upcoming weeks i hope to have something to show off.

Cheers
Jan Rune

gday Neilw, glad to see your about, have read some dood info from your posts. i purchased a sx3 spindle speed upgrade kit from LMS. installed and wired as per instructions, powered up spindle started up. hit e stop-spindle off within coupleof minutes heard a nice pop and then the dreaded sell of elec gone wrong. after investigating found the transformer on addon board blew primary coil and was for 110v. 110 - 8.5v. found a suitable replacement fitted it up and have had no luck getting spindle action. fuse on xmt board ok. do you have any suggestions where else a problem may of occured or direction towards fault finding this problem as i am stumped at moment?

Something probably went to ground. Look for blown tracks near the transformer.
Take a detailed photo of your boards and I will see if I have a circuits.
Those 110v things don't like 240v for very long, and there is a mini switchmode inverter there too.
What area in OZ do reside? Perth? A bit far away, but we could skype and do show and tell by video.
That might help you.
