Looking for a tabletop size CNC mill, something in the size of a RF30 or RF45. I am not sure what all is out there so I'm not sure what I should be looking for yet. I am also interested in buying a...

Thanks for the info but I don't think anyone will need the MC file after all :) I finally got it figured out.




Well that is where the problem was! I went down and set G52 to zero's, I had it...

I played around with the Haas a little more today. I still don't know whats going on but it starts machining approximately x-14 and y-6 from the part zero I gave it.
Here is the file, it in .dxf,...

Sorry, I should have answered your questions the last time I posted but I missed it. I am jogging to X0Y0 on the part and then while in the offsets menu with G54 highlighted I push the part zero...

Sweet, thanks. I was trying to turn it off in the machine definitions menu, but just in the wrong part of the menu. Thanks :cheers:




When I run the simulation in Mastercam everything looks...

I couldn't wait to check it and just my luck, that was not it. Anyone have any ideas for the offset.

Steve

Thanks for the help, I checked on the T90 and sure enough, there it was. Thanks again, Ill pay closer attention next time.

I have run into another problem as the day progresses. Here is another...

Well after some time I have my 1991 Haas VF-1 up and running. I am down to sending the post to the machine but that is where I am having problems. Here is where I am at so far. I can transmit to the...

Thanks for the tip, I am going to check for it but I have been busy with this project.

Well long story short, I had Mitsubishi on the phone about the old drive and I asked about a cross reference...

Thank you for the help guys. I was actually going through the code line by line and I found out the every 10 lines or so there was just a bunch of random letters and numbers thrown in. I am not sure...

Well I spoke to soon I guess. :cryin: I ran it yesterday for an hour or so trying to program it and I did not have any problems with the resistors getting hot. I thought everything was OK until about...

I completely forgot to mention, I changed the name to the Haas recognized o9999 name and I still got an invalid G code alarm. Do I need to leave in the O0 when I add the name?

Steve

Well I finally figured out the cable and I was able to send my short program to my VF-1. When I try to start the program I get an alarm for invalid G code. Any ideas? Below is my code;

Well I got the new transistor in a soldered it back to the drive board, made up some new cables to replaced 3 of them that were burned and voila!, it fired up and so far seems to be functioning...

Transistor came in from Singapore yesterday and I am getting ready to install them. I am trying to go through the rest of the board to make sure that nothing else was damaged when the transistor...

As for the wire duct I found some of what I need at McMaster Carr and they are about 30 minutes from me so I can pick some up on Monday.

I checked the output voltages from my Busk Boost...

Well, here is where I am at so far;


I do not have a transformer in my machine. The input power goes directly into the main breaker and from there to contactors and the rest of the machine. What...

I do not have a transformer in my machine. The input power goes directly into the main breaker and from there to contactors and the rest of the machine. What can I do to get the voltage down to 230?...

Some how two identical threads were started so to resolve any confusion, this is not the main thread, this is.

Well I am almost done with the rebuild on my VF-1. I went out to the shop today with the intentions of loading the program, setting up the stock and giving it a dry run. After powering it up, homing...

Thanks for the info, I just need to go down there and get to it. Thanks :cheers:




Thanks for the tip, I will shoot him a message and see what is available. I tried to get into a Haas class...

Well, its done!
Almost done any way. I still have to get the lights installed. I need to get a bridge rectifier on the way home tomorrow and hopefully get it wired up. I also need to tweak the door...

Thanks for the info. I have an older laptop I plan to use. It has a serial connection so I hopefully will not need a USB to serial converter but I have one if I need it. I also have what I hope is...

I don't know what the problem is but I have been doing tool changes with it while testing and I have not had any problems with it. I guess it just needed to be moved around some or it got bumped...

Thanks for the tips. I started to check over everything and I tested the transistors but I came up with nothing. Then I saw a bad solder connection for the main 160VDC power feed to one of the...

The new tool door brackets are completely different so I needed to get my new one modified and bolted up. Here is my new bracket installed.
...

I got the cable installed today and it went very well. I ran a few tool changes, without the tools, and it went well. Next I need to o a few changes with tools and do it slow to make sure that...

I have not tried to remove the MOSFETs yet but that makes more sense on the mounting. That will make them a lot easier to test and replace. :D
The link to DigiKey is for the correct mount but the...

Well I have looked all over and I have not come up with any solid info on repairing the servo drive boards for the older Haas brush style servo motors. I have 2 bad drive cards and it kills me to...
