This would be the best solution. Releasing the source code, all the configuration problems will be quickly solved and it will be also the possibility to create alternate versions to suit one's needs....

With the latest plugin version, the MPG mode is visible improved but it still looses a lot of steps.

This is a perfect approach:


And the most important thing is not to loose any steps....

Hello, I received yesterday my wireless pendant WHB04-L and I was impressed by the good build quality.
But after I plugged and set it up in mach3 I became so disappointed...

For me the handwheel...

Some more tests..



input voltage
output current
max rapids


42.2V

Yes this is the way I have calculated, 60% if the motor amps. But now it is at 35%. I am curious if at lower voltage the drawn current will rise. Will check later.



I will lower the voltage and...

I was thinking that probably the output voltage and current is different from the input but then why the psu is calculated by the motor amps rating? And I ended up with a huge toroid.

My stepers...

Hello,

I have just wired everything, and set the Vref at 2V with the running motor (I have the special rev.1.1 drive) and I got a ridiculous motor torque. Then I turned up the VR1 until I got a...

Hi all

I need to order my transformer and I'm not sure about the power I need.

My 4 stepper motors as controlled by THB6064 based drives.
I actually what to push the chips to the limits. The...

Hi D.L

My build is not progressing very well. I'm stuck with the linear guides, the steel flats I bought are not straight and it is hard ho have them grounded cheap at that length.

I haven't...

The holding torque will be the same as long you will give the 3A per phase respective 4.2A peak from the driver. But the torque will drop more rapid if you give less voltage. For your 4.2V and 3.2mH...

Of course it will be scaled down, which means I will not be able to run the machine as fast as I wish, but I hope it will be fine until I'll upgrade to 7A gecko drives.

There is a very good excel...

Hi lucas,

After finalising my machine design I calculated that I need more power than the THB6064 can give but I cannot afford better drives at the moment. Now the question is if I buy bigger...

If I got it right, the drive must provide the peak current which is 1.41 times Amps/Phase. This means that with the 4.5A drive I can run only a 3.2A stepper at its full potential.

Maybe I can...

Thank you both for the input!

Jerry, when I came across your big bamboo thread I couldn't go to sleep before reading every single post and that was 4am. You have a lot of amazing ideas, especially...

Now I'm mostly concerned about the weight of the gantry. When I started the project I was thinking to have it between 100 and 150 lbs but now the nearly 200 lbs sounds heavy to me.

I don't know...

Hello everyone!

After considerable reading here on the forum I started drawing the project and here I have the first completed version ready to share with you. I'm not very good at 3D designing so...

wow! your "2 axis spindle mount" is awesome (or how's called if has a name).

I was thinking to build something like this in the distant future.
What is your gantry weight, x-y screw diameter and...

Sad to hear this... From discussions I think it is a nice build.





Many thanks! I like your design, it looks sturdy and compact but you need to use big bearings or thin ballscrew

I made...

Hi Master,

Where are all your pics gone? I was wanting to check your rotating ball nut design but sadly there's nothing to see...

Thanks for your fast response.

Everything is more clear now. So the drive doesn't need to "know" the number of steps per revolution the stepper has? this is only the software's "problem"...

Hi lucas

After reading this thread and the other regarding the THB6064H IC I think that getting your drive kits is the best that I can get for a low budget "hybrid machine" build.

You along...
