Mini scout it all fits on one sheet so you can get it cut and built quickly unless you don't have the electronics for it.
Please keep me informed on this i use solidworks daily and it would be nice to use it this way as well.
I have been using this its harder to get it sharp like the supplied wire but it works good
Hey, Tks I'll look in to it.
First off i put the wrong torque spec in for the stock stepper its 54 not 64. So are you building it stock or are you modifying it? I ask because the nema motors i used wont fit they are too tall. There is another option that might fit and still give you more torque then the suggested motors. He specs out a 37mm tall 54oz torque stepper, 17HS15-1504S-X1 is a motor i found on amazon that may fit and give you 64oz of torque it is 39mm tall stock is 37mm tall so i think this will work. If someone has a stock setup can you tell me how much clearance you have below the stepper motor and the floor?
Yes thank you. @effdubya there are quite a few 64oz or 54 ncm nema 17 steppers up tob 40mm tall that would leave you 3 mm clearance not much but it should work.
I may have to give the 17HS15-1504S-X1 you listed above a try. My Y stepper seems a little weak, and seems to skip steps sometimes. I’ve checked the Vref and it’s at .7v and I’ve swapped the driver as well. But it still randomly makes a “click” then seems to be slightly out of position.
I’m really having a lot of fun just tinkering around with it. Other than a few things to try and stiffen up the cutter head, the only real mod has been a linear rod and bearing on the other end of the Y. Really not needed, but i have a bunch of surplus bearings and stuff at work. And like i said im enjoying just messing around with it. (Edit) Its cutting pretty well. Not perfect, But im not expecting perfection.
The A4988 drivers should be run at .6 vref (vref x 2.5= 1.5 rated amps) if you change to dvr8825 driver you could run at .75 vref (vref X 2 = 1.5 amps) so you may be over heating your driver. Now you can remove the 12v to the uno and power the shield with 24v this will also help increase the power to the stepper but you will have to modify a few things to get this to work.
Nice. I found a set of linear rods i want to do and move the 2040 to the Y and stiffen it up allot. I am also working on stiffening up the slop in the head but after my last couple of sheets with my new setup i might only gain a small mount of improvement.
Stock both drivers measured .66v and I though I saw in one of the threads that you should shoot for .7v Ill keep a eye out for temps, and maybe lower the voltage.
Once I get the Y motor sorted, I want to work on getting rid of as much slop out of the cutter head as I can. And the Y motor really is that bad. But I put a Indicator at the home position, then run a sheet. If it didn't make the click noise it will come back basically prefect +- .002 If it did skip, it will be anywhere between .02 -.03 out. Doesn't really matter, but...
Did you actually cut or just test run? The extra drag of cutting might make that skip worse. Basically it shouldn't skip at all it just allows for inconsistent cutting and that's not good.
