Spindle too heavy?

[irving2008]

"Doctor, I have a pain, what could be wrong with me?"
"a pimple or cancer, take your pick"


* What's the machine,
* how is the z-axis driven (e.g. belt/pulley sizes, ballscrew/pitch, leadscrew/pitch?),
* what is the z-axis motor (NEMA size, torque, current rating.)
* what voltage/driver board/PSU
* What velocity/acceleration (original/new)
* what's the weight of the two spindles
* anything else that might be relevant

I'll Take a wild guess it's 3020/6040 or some rubbish from Devon.!!

Springs cost pennys so try them is the easy answer to that question. They will help not indure but you obviously have issues so a better solution is to heal problem not cover it up with parcel tape.!

Give the details irving asked and we can advise more specific.!

Hi. it is a 3040. It uses leadscrews and nema24 motors. I will check the power from the supply shortly and see what its pushing out. The electronics are all original. It is about 3.5 years old now and is in the process of being upgrades(ran out of cash while building my 1200x600 laser). :)
I will check the rest of the details shortly and let you know.

Thanks. Isaac

The steppers are 2.5a, 1.8degree steppers. Voltage is 24v I believe, cant find my multimeter to check.

Original accel was 80, Velocity 400 (MM for units)
New better sounding values are 120/500

Spindle is about 6kg, old one probably less than 1kg.

Thanks

To get around this correctly will be uneconomical because you'll probably need to replace most of the electronics including motor. Only you can decide if the machine is worth the cost and trouble.?

I would just devise some counter weight like the springs idea has it will be a lot cheaper and probably easier.
