I would assume that you are referring to the motor inside the scanner assembly, not the drive motors.
Is there a mirror attached to the magnet assembly which is mounted on the shaft of the motor?...

the fact that the green light illuminates when a pattern is moved under the lens tells the phototransistor is working.
Is the mirror magnet assembly turning? It needs to be rotating for it to trace....

When I worked there they sold the phototransistor as a separate item.
How do you know if it is defective?
They are painted with a flat black paint on all sides except one.
If the paint comes off...

I have dongle if you want to buy it

Make sure there is not a code for metric operation in the program.
The Lynx wills ee this code and automatically switch to metric for the program, all other operations will remain in imperial or...

Where in Canada are you located?
If there is a problem with the head you can always send it in for repair & calibration.
The problem could also be in the signal processor card.
On this card there...

Of course there would not be a free solution. You need to purchase the software to make it communicate. The original owner of the machine woul dhave had the software supplied when they purchased the...

Too bad I didnt read your post soon enough
We manufacture the Hl90 and we make bolt on encoders for them, plus we have a CNC that is also connects readily to the HL90.
The bounce is caused by the...

Any luck with your Lynx?

Did you ever get your questions answered?

Let me know what you need. I have worked on over 5000 HL90's, I like to think I know them. If you need info, instructions on how to add a CNC or just a manual let me know.

Those parameters are all fine. What is necessary is to have the program in your host computer to have the same parameters.
There should be an 'ini' or 'config' file in the root directory of the...

The RS232 settings should match the settings of the communication software in your host computer.
What is the communicating software in your pc?

Very common problem with HF plasma systems. The first thing you should do is go to a plasma manufacturers web site, such as Hypertherm or Thermadyne and research the proper grounding techniques for...

looks like you will need to switch to something else. Promotion Nest does not do splines. Its as simple as that. It will do them in a series of small arcs.

The KAR control is also called Promotion, it is made by Promotion Controls in the USA. The company I work for manufatured these controls for Promotion for about 8 years. They are a good control but...

You cannot run it using any program. The first step is to add a CNC. Its the CNC that runs the programs not the tracer.

"I guess you can get advice here... but the best advice you can get is real world going out and looking at shops with Koiki's in them or hop on a plane to Japan or China and see them getting...

Your machine already has motors and a complete servo drive system. I dont understand why you would add additional motors. Can you please explain?

to upgrade this with a CNC is quite easy. I have done dozens myself. The HL90 is designed to connect to a Picopath. Its just a matter of spending the money. A new upgrade package will cost around...

In order to use any software you need to have a CNC installed. The HL90 will also need a CNC interface installed in it. It is a plug and play interface. It will also need encoders in order to operate...

The floating head is a pneumatic type torch hieght control, you set the height and it keeps itself at that height by rolling on balls across the plate and is held in place by the air pressure,...

Im afraid I cannot help you there. I have never heard of that type of CNC control. As I said Koike uses different types, the CNC controls that we manufacture and that they purchase from us are Hybrid...

Koike makes good machines, one of the world leaders in profile cutting machines. Would this be new or used? They use various CNC manufacturers for their controls. Which CNC is on the one you are...

What communication software are you using?
Or do you have this problem solved?

That is an HL90 tracing head you have on that machine. Extremely reliable and decently accurate. A larger servo amp can easily be attached to that and still use the tracing eye. The speeds of that...

Did this problem just start or has it happened since you owned it?
What are you using for communications?
What nesting software are you using?
Does it pass the rs232 test?
Does it have a floppy...

This is typical plasma noise. Isolate all your electronics from the machine. Run a thick braided wire from the gantry to the ground rod, hopefully you have a ground rod. If not put one in and make...

You have a grounding issue. make sure the bridge of the machine and the table are both grounded to a ground rod driven at least 8 feet, 2.5meters into the ground.The best ground rod would be 3/4 inch...

First off, where are you located, there are machine building companies big and small all around the world. I can rhyme off a number of companies that I do business with on a daily basis that would...
