Re: Roland iModela iM-01

The two primary purposes I would use a CNC mill for: Cutting copper clad, for prototyping circuits. Cutting plastics and/or molding materials for making plastic enclosures/parts (small product prototyping)** My current line of thinking is to buy a mini lathe first, for myself... Then, convince my bo...

Thanks for the followup :) My only experience with Roland products is with a Picza scanner - I haven't had the opportunity to play with a Roland mill.

Re: Roland iModela iM-01

Hrmmm... After diving a bit deeper, I don't think the iModela is for me. I still think it's really cool - I certainly would use it if I had it (and perhaps push capabilities prod/poke like I have with the Up! machine). The reason I don't think it's for me: I would be using it too much... The spindle...

Re: Noticing the new printer

The biggest differences I see.... * Stepper Daughter cards removed - likely a cost down move * A relay has been added (ha! the product I work on used this very same relay in the past, but no longer) * I see two switching regulator circuits... 5V and 3.3V? Or perhaps a 5V for the MCU and an isolated ...

Ghostbusters! Halloween 2011

A combination of printed parts, paper backed foam core, MCU+LEDs+Software, plastic tubing and pipe, fan-made stickers, a crap ton of work and hitting a hard deadline (party) before finishing.

Re: Roland iModela iM-01

Great, I like the small foldable design! I would love to have this small machine sitting on my desktop,besides my UP! I found a price mentioned of $1000, which is a bitt steep. But I'm sure some clever guys will make an open source derivative soon for 1/10 that price :lol: $1000 is cheap! It seems ...

Re: Variable perimeter layers for UP?

Funny, I was just telling someone about that and why I would recommend an Up! or a BFB3000/3DTouch for a hackerspace instead of an Ultimaker/Makerbot no matter how attractive they look on videos and on a price front. You mean they pass Trebuchets famous 'mother test' :lol: I'm confident everyone ha...

Re: Maximum operation temperature

Ideally, there'd be a separation between the various electronics and the build chamber itself. that's what those really expensive printers do. There is :p The bottom cover separates the electronics from the build envelope. The trickiest part is getting cool air to the extruder heat sink.... Stratas...

Re: Print head seems to have failed

I haven't touched any of the connectors (apart from lately, when trying to fix it). I can't really try another withdraw as I can't get it to extrude in the first place now, so there's nothing to withdraw unfortunately. Yes it's heating up properly, I can feel the heat coming from the nozzle area. I...

Re: Electricity Usage

I have my printer connected to a Kill-a-watt.... Sitting idle, it consumes about 22W - that's pretty much how much power is needed to run the stepper motors at any point in time. The rest of the power is consumed by the heaters. That will depend on how cold the ambient temperature is. For me, once h...

Re: new official perfboard kit

edit: I just looked at the perfboard on the PP3DP site and, honestly, I think DIY with radio shack board might be a tad bit better, especially for the money. RadioShack perboard is $3.39+tax and is the perfect size that you just rotate the platform until it meets up with the edges of the 6x8 board,...

Re: How to stop nozzle blockages; and fire risks?

First, the temperature is too low to cause the plastic to catch fire. The marks you see are from overheated plastic. Left long enough, it will turn black (carbonized?) but will not ignite. When my nozzle is too close to the platform, I get little plastic nubbins stuck in the perfboard (just as you h...

Re: Thinking about getting an UP! and have some questions...

Anyone know why that particular port used to require a 5V power adapter rather than outputting 5V? I do! The original design that was shipped out does not have a regulator to power the MCU. That extra 5V power supply actually powers the MCU - you could have the printer "on" and communicating with y...
