Re: Rostock mini playing beethoven music - 10 years ago

I wasn't even aware that any delta firmware could command motors directly. So using your firmware the deltas can play polyphonic sound, too bad I have only Mega2650, I soo want to try that. And I like your idea about using extruder motor for the second channel. Here is another one - what if 10 people get together and make 10 deltas play a symphony

Rostock mini playing beethoven music - 10 years ago

A week ago I was watching a Youtube video about CNC machine playing music and tried to make my printer do the same but the result wasn't music at all I gave up when it hit me...deltas behave differently than cartesian machines, what if I use only Z axis ? So I present to you a Rostock Mini Pro playing the song "Für Elise" by Ludwig van Beethoven: http://youtu.be/XCQJgXlSfpk I wrote step by s

Re: Can i use Nema17's with a smaller holding torque with a Rostock Mini ???? - 10 years ago

I investigated what kind of motor is used on my Rostock Mini and found out it has holding torque 35 N.cm. It is about the same motor as the one you want to use but coupled with a 5:2:1 planetary gearbox. The gearing in the gearbox multiplies the torque so this same motor wouldn't quite have enough torque for a direct drive. It is Nema 17 motor HUISITONG 42BYGH403AA:

Re: Can i use the Rostock mini with a Ramps instead of a Sanguinololu ? - 10 years ago

According to the RepRap website: Quote"It is recommended that you get approximately 13.7 N-cm (= 0.137 N-m or 1400 gf-cm or 19.4 ozf-in or 1.21 lbf-in) of holding torque (or more) for RepRap axis motors to avoid issues, although one stepper with less has been used successfully. For Wade's Geared Extruder (most widely used one as of 2012) it is suggested to use motor that is capable of creating a

Re: Printed Pusa parts don't fit well (too small) - 10 years ago

Models are polygon meshes, so all curves are actually segmented polylines and a polygon always has smaller area than its enclosing circle http://hydraraptor.blogspot.com/2011/02/polyholes.html There are more possible reasons, wrote an article about them here.

You won't get an exact answer for your setup, it depends on speed, temperature, filament, bed material, cooling....... I use "trial and error" approach to find out what is working for me and that never fails.

Re: Delta Max Height Config - 10 years ago

The delta printer working area is not a cylinder, it's like a rocket shaped at the top. This means that you can't print your max Y or Y sized objects all the way to the max Z but a little shorter. For Rostock and Kossel look at the first shape with 3-DOF. This is the picture from the document Architecture Design and Optimization of an On-the-Fly Reconfigurable Parallel Robot

If your wiring is correct that leaves only firmware and stepper drivers as possible sources of error. Get my Repetier firmware file here and compare settings with yours.
