Quite an Unusual one

[Boyan Silyavski]

HI,

yes i have an update.

First one of the piles of steel at the previous photos now is welding and fabrication table, the other pile with the long pieces now is a shed in front of my garage where the machine is. At the link above you could get idea how to fix the UPN to the bed









Now about the machine itself. Cables mounted and ready to run. I had some problems fitting the cables cause i made the error underestimate how big cable chain i need. I had some serious cable chain but it seems i needed even bigger.
Some of the encoder cables were shorter so i had to invent here also. Most cheap was to use HDMI cable, i hope it lasts some time.

Now the biggest problem. I can still not make run the machine. Reason being that although all is connected and programmed from Mach 3 side and from Galil side it would not move.

So i read 10 times the servo and the Galil manual / each 400 pages/. At the end frustrated i started trouble shooting. Checked 1 by one all cable connections cause the servos were tripping, cleaned contacts...this took a couple of days. At the end i discovered that when programming the servos somehow i missed to program correctly the motor name of 2 of them, hence the problems. So more or less all is ready here, still have 1 enable wire to 1 of the servos not working well so i have to rewire that.
Jogged the servos from the software and tuned them for a second.
That servos are incredibly fast, smooth and silent. The machine moves like crazy fast super silently. I directly jogged the Z assembly left right on the gantry 10-15m per min. Its scary.
Good that the frame is balanced horizontally. yeas i have 10 cm deviation on the floor so i used 30-35 square wood pieces leveled them and the machine is on top of them.

So the machine should be running any minute but 2 weeks i couldn't manage to make the Galil board work. Yes, it works communicates, switches signals and so, but still not able to make it speak / pulse/ to the servos. And on top of that i burned the COM port from changing cables. So i could not now change the servo type of signal expectancy. GRrrrrrrrrr!! Now have to wait for new COM board cause where i live...

I asked about help with the Galil at Mach forum, Galil forum, nobody... So after 2 weeks i discover that i have to issue MT command to change the type of pulse it sends. It may be the greatest board but with nonexistent support, no schematics of connection... maybe i did a mistake not contacting directly support, but from what i saw in their forum-please read the manual its explained there. yes its f***ng explained but its 400 pages manual and i am reading 3 of them at once and on the way learning new terms that i had no idea yesterday what that even means, so a bloody connection diagram for every application example and step by step instruction would be great for stupid people like me and the 20 engineers that asked the same questions...

So i am still stuck, last effort these days, then it goes off the machine cause i will receive 2 Pokeys boards, so one goes there. Will leave the Galil apart, mount it in another box , study it and use it in another machine. And then bloody sell it :-)

So any day soon it will be fully alive, then i will move the gantry around and mount and level the ready UPN140 pieces for the working table bed to be level, Thats why i need to move the Z around so i measure and shim where necessary.




Here where is the PC, the VFD and so on, at the entrance. Switch on the machine,mount piece, Mach3, program run, then go out and close garage door. The garage=Big enclosure for the machine
