Really nice project!

Where in Sweden do you live? I live about 50km from Halmstad. Are the old parts for sale? I don´t have the same servo cards, but you might have some useful parts.

How much does the conversion cost?

Hello! I haven´t used mine in a long time, and the last time one om my servos didn´t start so I´m pretty irritated on mine :oops: It´s a computer that has to start, it´s good to have an external keyboard (a really old one with the giant round contact), that you can attach on the side where the flopp...

Nice work, the machine looks amazing!!

Looks really nice! Good work

I sold an overlay last year to someone here, the shipping was about £5 to GB so I asked for £10 for one overlay. I can send two overlays for £14 (I use Paypal).

Would be nice so se your machine working on Youtube

I haven´t used the machine so much, so I can´t say it´s reliable solution. But it´s has worked the times I´ve been running the machine, maybe 5 times since this thread

I have a TU150U, but probably the same procedure, did you see this post:
viewtopic.php?p=20455#p20455

Maybe it´s like on my TU150U, there is a possibility to adjust the "spindle override" on the operator panel which gives a higher or lower speed. In your case it could be possible that it´s set on 140% override.

I tested the Gotek USB Floppy Emulator on my Harrison TU150U today, and got it to work. Have not done any longtime test, but it work fine tonight when I was making some test on the lathe. I tested different setups on different "floppys" on the USB-memory, and the 4th one with DOS 7.1 did work! https...

Made a little video too:

I just entered a program from the manual to test, so don´t ask what it is

Thanks, I hoped it was like that

This is my first test in the machine!! I´m happy now

I think I got it to work decent now!! :D To get rid of the bananas-movement, I changed SLAVE_GAIN_X 1 to SLAVE_GAIN_X 0.5 and when I measured the movement, 1mm became about 1.23mm IRL, so I tested to change: SLAVE_MMCONVERT 500 to: SLAVE_MMCONVERT 410 and got a decent result!! Wihooooo! Just to lear...

Actually, today I managed to get pretty far in my plan to get this machine to work again! https://tipsarn.se/bilder/170506_01.jpg But it´s a problem with PID-parameters or something like that. When using 1mm step, it goes bananas. https://tipsarn.se/bilder/170506_02.jpg Made a quick little video, sh...

I will not use them all, so that is possible, will send you a PM.

Hello again! I bought a used servomotor from Germany and today I got a kit with some drivers and smaller servomotors from Angel-Tech here on this forum! I changed the motor a couple of weeks ago, and with my old "communication-card" in the drivers I got today, it looks like this! Really nice to see!...

I would like to buy some parts for my Harrison TU150U -96

I need:
1 Baldor servo motor BSM80B-175AA 1.63Nm
1 Baldor servo drive DBSC1002-AAA-24

or...

some alternative to change both drivers and motors to something else if it´s possible.

Send PM or mail me at:
edis AT backspegeln DOT com

I took the running servo motor and connected it on the "burning position" and started the system without putting AC-power to the drivers, and the light was still red on the servodrive. It should turn green... This is the drivers, and it´s the on at the left that is bad. https://tipsarn.se/bilder/160...

NOAIR 1 did the trick :D https://tipsarn.se/bilder/160823_03.jpg Thanks! I was able to start the spindle today and ran it at 100rpm both CW and CCW. It didn´t start yesterday because I had the door open :lol: I was so happy to be able to got the system running yesterday so I didn´t reflect over that...

OK, thanks!

I just have to buy a servomotor first before it´s possible to home it.

Thanks! :D I found one of my old laptops, hade one with XP and diskdrive, so I created a startdiskette and put files from your Drivers2-folder and also TU150-files in the root of the diskette. And boy, this was a nice view! https://tipsarn.se/bilder/160822_01.jpg https://tipsarn.se/bilder/160822_02....
