Re: Nema 23 upgrade power supply

Just for the record. I've been running my machine using the 48vdc power supply set to produce 24vdc for a while now with no issues. I am upgrading the z-axis to use a nema23 motor next week so will see how it goes also.

Re: Nema 23 upgrade power supply

Thanks guys, I've wired the grlb shield to the power supply and changed the output voltage to be just about 24 v. I ran a test and everything is working fine. The gShield will not be able to drive those motors at their rated torque, but, indeed, they will be better than the NEMA 17. You may get bett...

Thanks, seek rate is what I was looking for :) I've changed it from 500 mm/min to 1000 mm/min and it looks much better now!

Re: Using my Dremel without the motor brushes

Isn't your mains 230 V? As far as I know, the DW660 is made only in a North American 120 V version. You'll need a hefty transformer for it. I was planning on buying one of those (around 67 USD) or a similar one over ebay/amazon, it can serve up to a 1KW. Do you think it will work with no issues or ...

Re: Using my Dremel without the motor brushes

I don’t see how that can be made to work. It’s an electro-magnetic motor arrangement. You need the brushes for the contact to provide the current which makes the motor turn. Where are you? New Zealand :), there was a holiday and the hardware store (Bunnings) didnt have those in stock so I had to pl...

Changing feed rate on the fly

Hi,

Is there a way to change the feed rate while the machine is doing a job? I am using the Universal gcode sender. I've tried a couple of other gcode senders but couldnt find that feature, either that or I am not looking in the right place :).

Thanks!
