Re: Another first drawing, and another pen holder - 16 years ago
True. Best bet then would be to build your strap, print a set of parts for yourself, build your darwin, then print a set of parts using both your darwin and your strap so that print time is dramatically reduced. Yes? Dementedby Demented Chihuahua - Reprappers
Re: Possible cheep laser cutting service? - 16 years ago
Thanks, Ian! Much better than 5kg. Also fits in with the 5lb spools being able to print more than 1 reprap. One reprap is pretty good for $30.33 in ABS. Now if we could only bring the print time down to a 24 hour period... Dementedby Demented Chihuahua - Reprappers

Re: Possible cheep laser cutting service? - 16 years ago
Are the printed parts REALLY 5kg! This seems not right...I remember from the before time, in the long long ago, that it was thought a single order of filament from RRRF could print one OR two darwins. I'm I totally off here? Can we get vik to pipe up and tell us the ACTUAL weight of a set of printed darwin parts? Dementedby Demented Chihuahua - Reprappers
Re: Another first drawing, and another pen holder - 16 years ago
Ru, yes the current stepper/darwin setup is plenty powerful but most of us don't have darwins afaik. Straps are pretty prevelant, if not most common, and are not nearly as well designed as a darwin for the most part. But, yes, the extruder still needs a lot of work. The accuracy has been addressed by the encoder and valve recently put on them but I think some other method of driving the filamentby Demented Chihuahua - Reprappers

Re: reprap host software - Tools menu... - 16 years ago
That's probably why. The Arduino, I think, just passes on messages to the appropriate driver boards. If there are no driver boards there, I'm not sure what would happen. Change your pref-settings so that it is set to "nullcartesian" under the "Geometry" option int he preferences page. That should fix things...famous last words! hehe Dementedby Demented Chihuahua - RepRap Host

Re: Pot based position system - 16 years ago
I like it. My big hold up on printing speed isn't the extruder as I thought it would be but the cart-bot. If you can get it to traverse at a fair clip you have gone half way to solving a big problem that I, at least, have been having. Also, since it appears you are using a simple brushed DC motor and gear train, you cut out some fairly expensive components. I'm very interested in seeing the x-axby Demented Chihuahua - Mechanics
Re: I need help with a custom ball bearing joint - 16 years ago
Low tech idea from another source, not me... use a rubber band to pull the head around. Loop a rubber band around the handle that you use to pan the head and pull on the rubber band. The band will even out any jerkiness caused by your hand and body and give a smooth glide to your pan. I saw this in a clip online somewhere. Worked really well then you don't have to worry about paning being jerky.by Demented Chihuahua - Mechanics

Re: Extruder Exerciser doesn't work? - 16 years ago
I think I had this problem while building my strap when I didn't have the thermistor plugged in correctly. The machine would just shut down on me. Check ur wiring again for the heater circuit. Make sure there are no breaks in ur lines--ie test continuity with a multimeter--so that you know it should be sensing something. I assume you have given power to the board?

Re: reprap host software - Tools menu... - 16 years ago
More info. What exactly does happen? Does anything open? Any windows? Just nothing? Do you have your geometry set to nullcartesian or cartesian in the properties? This might affect things. Dementedby Demented Chihuahua - RepRap Host
Re: Odd behavior - 16 years ago
um, still working on a repstrap--mine not the schools--so I'll still be around here just posting rants and complaints about *different* annoying problems! hehe I'm re-doing a lot of my previous work on my machine. I left it in quite a state of dis-repair when I started work on the OIT RepStrap. Things are looking much better now and I am making HUGE progress at a much faster rate than before.

Re: Heater Calibration questions - 16 years ago
Okay, I'm no expert but... Now that we have the failsafe in place above...I used this site to calculate the regression coefficients here The y-axis intercept is one value and ur x-coefficient is the other. Simply plug these into the properties page. I'm not sure which is which as I'm at school right now but the bigger default value in the preferences page will be the y-axis intercept.

ahahn, ...sadly I do not have anything new to report. The machine is back in it's permanent home at OIT in Klamath Falls Oregon while I am in my new home in Portland Oregon.

Re: My first Arduino powered drawing - 16 years ago
Looking very good! The speed up is admirable. That's a bit slower than I think the extruder pump for the OITRepStrap can keep up with. I'm really looking at servos more and more just cause the speed issue bugs me so much. oh hum...must learn more stuff. Dementedby Demented Chihuahua - Reprappers

Re: Odd behavior - 16 years ago
Using 0.8.3 software but Arduino firmware 0.3. Gets up to step 5 but take out all that z up and down stuff--my pic strap does that too but the arduino never has. Add to this the fact that the extruder turns on and runs and the software thinks its going somewhere--evidenced by the fact that when I cancel the build it tells me it traveled some random distance. It' thinks it's working but nothing haby Demented Chihuahua - Controllers
Re: Reprap-able generator: STL files included! - 16 years ago
tried that with a lot of sites. Not so satisfactory. I'd give you a block to translate but i'm not really sure what i want to know. I like to peruse a site and find the interesting bits and then learn more. Can't do that through an interpreter. Thanks anyway. Dementedby Demented Chihuahua - General

Re: Odd behavior - 16 years ago
Steve, Played with those. Some success. It was the FastSpeed that was the problem I think. Set too hi for it to home. Have it set lower now and it now homes at the beginning of a build. However, and much to my disappointment, the other problem still remains. I can get it to go through the homing process, the move to the start build position, the heater turning on--though not heating up all theby Demented Chihuahua - Controllers
Re: Extruder help - 16 years ago
I've got a really old extruder from RRRF but it is pre-january. I don't think it really matters as far as compatibility goes other than you not having an encoder or solenoid. I wouldn't worry too much. If you need build pictures you can look here at what mine looks like: Hope that is what you needed. Don't know if it is. Sorry wasn't more help.

I think its a 350 watt pc power supply. Nothing big or fancy but we know it's surge protected and that if we try and draw too much from it on purpose, it shuts down. That's why this doesn't make sense. Dementedby Demented Chihuahua - Controllers
