Re: stuck again!!! - 14 years ago

You need another Arduino (Sanguino, etc) to run the extruder board. Edit: unless you do some serious hacking of the extruder board firmware. Not sure how you would even go about it.

Re: Plastic Parts Dimensions? - 14 years ago

I just use for measuring STL's. It's free, though Windows only. It can measure point to point, line to line, circle center to circle center, or any combination of the above. It's quite useful. Edit: can't remember if it can measure angles, but they would be easy to calculate using three point locations.

Re: new website I found, prototypetoday.com - 14 years ago

Been a while since you posted here TimRuffner? What was your previous username then?

Re: Host install problems. - 15 years ago

Why would it be requesting that much RAM? I run the host software on a several year old computer with 1 GB of RAM under Windows 7 and have no issues at all.

Re: mixing things up - 15 years ago

My motors (with Gen 2 electronics) are permanently enabled. It's not a big deal, and doesn't hurt anything.

Re: Wades Question - 15 years ago

I have three NEMA 23 steppers from alltronics, they were only $17 a piece and very powerful. They're working great and seem to be very high quality.

Re: 6v steppers - 15 years ago

I run 0.9 degree 3 volt steppers with 12 volt supply, and have no issues at all.

Re: frosted glass build-platform??? - 15 years ago

Are you going to print PLA or ABS? For PLA you don't need a heated bed, and can just print on blue painters' tape on top of any flat stiff surface.

Re: First print..! - 15 years ago

I print PLA on blue painters' tape. It works great!

Re: Geared Extruder Nozzle - 15 years ago

I wish I had known you were going to make these before I bought one of your nozzles I do have to say though that your machining is excellent, and so far the nozzle I bought is working great. To everyone else, I would definitely recommend doing business with reifsnyderb.

Re: 3mm PLA Filament - 15 years ago

I ordered some 3mm clear PLA from them a bit ago. They have good prices and ship quickly.

Re: Extruder barrel questions - 15 years ago

To prevent PTFE bulge, just get a 1/2" copper pipe connector. It fits snugly around the insulator (I actually had to hammer the insulator in with a soft-faced hammer). That will keep the PTFE from bulging and should cost less than $1 at any hardware store. You might need to file down the stops if it has them on the inside.

Re: Where can you get PLA? - 15 years ago

How about here? I just ordered a 5 lb roll of PLA in natural color, should be here today.

Re: stepper motor wiring & color codes - 15 years ago

This isn't a forum for helping random people from the internet use stepper motors. This forum relates to RepRap. If you want help with a specific stepper for something other than RepRap, you really should try Googling it or asking somewhere else.

Re: Bootstrapping Mendel with McWire. - 15 years ago

I am only able to get about 4 mm/s out of my McWire. I'm not quite printing yet though. I plan on converting it to a belt driven X and Y axis, which shouldn't be very difficult. I'll post back if/when I get it done.

Re: McWire Cartesian Bot v1.2 screw sizes problem. - 15 years ago

The holes are sized to be tapped. Once you tap them the screw will fit perfectly. If you want the screws to instead go through and secure with a nut, you will need to drill them out to the size of the screw.

Re: MakerBot Plastruder - 15 years ago

You just have to check back frequently. It's been in stock more than a few times in the past few months. I don't know of any other ready-made extruders, but I have seen some made that are really simple.

Re: McWire Extruder Mounting - 15 years ago

With the McWire, it ends up being 1.25 mm per revolution for all three axes, which is 32 times slower in the X and Y than the Darwin. Hence the reason for me switching it to belt driven. It looks like it will be quite simple to do, I just need to get some belt and pulleys.

I never get emails from them when things get back in stock, despite making sure I had clicked "Sign up to get notified when this product is back in stock".

Re: McWire Extruder Mounting - 15 years ago

I have both a complete McWire and a complete MakerBot extruder. I haven't gotten it mounted yet, but will most likely use some angle aluminum. Also, I will be converting the McWire to belt driven X and Y axes, as the screw drive is just too slow for reasonable build speed. I'll document both on my blog when I have time.

Re: US source for 2.54mm screw terminals? - 15 years ago

1/10 inch. I'm pretty sure that's a standard screw terminal.

Re: Welcome to the new subforum! - 15 years ago

This seems like a good subforum to open up. I'm just about to the point of getting my RepStrap printing, I'll start posting here with my issues/successes.

Re: PWM driver extruder problem - 16 years ago

sounds like you either have a short or are trying to pull more current through the PWM than your power supply can handle.

Re: atoma ring - 16 years ago

I've never seen those before. Pretty cool!

Re: casting aids for metals - 16 years ago

That's exactly how Jay Leno uses his Dimension 3D printer to make metal parts for his cars.

Re: gen 3 electronics and z-axis - 16 years ago

I'm sure someone else can chime in, but I remember there being a setting to enable the motors when they are not being moved. Unfortunately I cannot remember where it is.
