Tom,

That"s the way I was headed just making sure it wasn't already handled elsewhere.

Thanks.

Ray,

Sorry but that is not how it is supposed to work. I should not have to worry about the position of my overrides when cutting a thread. Any machine will ignore where the pots are set at when...

Tom,

I am having an issue with the FRO on my lathe, if not set to 100% during a G32 the pitch is not correct on a thread. These are controlled through my .ini file are using analog pots. I did not...

Tom,

Thanks that is exactly what I was looking for. :) I will increase the maxI and put in some integrator.



Yes I agree. I had done this on my first project when learning the C program and...

Hello All,

I need a little advice in tuning the latest project. I am using the Snap Amp and here are some specs.

-ABB DC Brush Servo motor 22 amp max
-2500 count differential encoders
-Antek...

Tom,

You are correct it accepted the 400K quad counts per second. I wrote the new pulse train calculations and have it working perfectly through KMCNC. Thanks again.

Tom,

Thanks for the reply. I think that will work. The servo is 10,000 ppr and at 2500 RPM it would be 416,666 pps....so 400,000 will work. I will experiment as it tells me I am limited to 200K in...

I am confused on the options I have for step and dir output and need some help. I have a KFLOP with 1 Snap Amp and a Kanalog board. I am putting a servo on the spindle of a lathe and need to use the...

Just an update,

The plasma table is fully functional. Thanks Tom the code worked fantastic. I had to tweak the math on my height adjustment in the PLC once I could see the usable range of the...

Tom,

This is great.:banana: I have some questions.


Couple of issues here. I was not aware KFLOP could handle an analog signal without Kanalog. The PLC was used to provide isolation between...

I am to the next phase of the plasma table which is getting the Z axis to track the material. This is being done with a PLC. I am reading the analog output from the plasma cutter into the PLC, the...

Tom,

That did it. I was not using the sync option and that caused the problem. Now when the M100 completes my machine coords remain unchanged.

Cheers

Tom,

I am trying to offset the Z axis on a plasma table to find the material. I am doing something wrong and need some assistance. I am using KMCNC version 4.33cc. My test G code looks like this....

Tom,

Thanks so much for the detailed explanation. I believe I am getting a much clearer picture of how the PWM operates and it is what I am looking for. To make sure I am understanding. There are...

Tom,



Not sure I understand what you mean exactly so more information is better than not enough.The mosfet will be switching the low side (the dc that does the work).If you are refering to the...

Hello All,

I have decided to retrofit a wire EDM. The machine is a 1996 Agie Sprint 20. The servo side of this is straight forward and easy, DC brush servos with encoder feedback. The wire feed...

Hello all,

Making a plan for the next machine that is using Mach 3 now and will switch to KMCNC. Hoping to draw on some of the experience here.

The machine is a small gang tooled lathe similar...

Awesome.

Thanks again.

Yes, the slider moves up and down but I have to push the apply button separately. After playing around a bit this is only happening on the SSO. The FRO will take affect after a short...

Aarwhy,

It sounds like you are refering to the work offsets already in the program. G54 thru G59.3 will do exactly what you are saying. A G53 will return you to machine coordinates. If you check...

If I drag the slider with the mouse it updates properly. I have my look ahead set low for this reason. Just was wondering if I missed something when I copied the code into my loop.

Hello,

The SL1 Lathe is nearly complete. Run a hundred parts or so and working great. I have the FRO and SSO pots working but I have to hit the apply button after I adjust the pot. I used the code...

Need help with the setting of the tool table.

Here is the sequence.

The X & Y & Z are jogged to a position.
Press cycle start, the M101 will execute and do 2 things.
1. Update the Length...

Thanks for the replys,

I am writing a tool setting routine and just attempting to simplify the code.

Here is what I have now.

Hello,

Is there a G code supported that will allow a line jump? An M99 P12 will jump to line 12 for example on a Fanuc and some others . I have also seen GOTO used in the G code.

Thanks.

Hi Tom,

Using version 432a.

Had to fight with the MasterCAM post but got it to output in radius. Working great now.

On a separate note....Is there a variable that changes after...

Tom,

I have searched a bit but I an unable to find anything concerning the issue I am having on the new lathe project. When using a G2/G3 I get an error:

"Radius to end of arc differs from...

Tom,

I see now :o. After closer examination I understand how this works.

Thanks.

Tom,

Thanks for the heads up. I have this working and taking cuts, works great. In regards to the G32, I have it working although it is not making the 45 deg pullout and leaves a groove at the end...

Hello,

The Mori SL-1 project is up and running. I have a question on the tool offsets. I am using version 4.32a.

In the tool offset screen the offset that is labeled Y I assume is just a typo...
