Hey everyone. I heard some interest in a group order for glass. A while back i had requested a quote for bulk ordered glass, and Atkinson Glass offered the best prices around. I've asked for quotes on the following sizes A) 20.5 x 20.5 x 0.25 cm 20.5 x 20.5 x 0.25 cm C) 20.5 x 20.5 x 0.125 cm D) 20.5 x 22.0 x 0.125 cm Ive requested for the glass to be Tempered, beveled edges, and 0.5 cm radby CidVilas - Idaho RUG
@kwhutto: Very cool find! There are some pretty ingenius techniques in that tutorial. I like the captured nuts.by CidVilas - Idaho RUG
Yeah blu Mendel or Blendel as I like to cal her, is built and printing. You can see pictures of objects I've made in my flickr photostream.by CidVilas - Idaho RUG
You are building a Sells Mendel, right? If so, i'd recommend going with 1/4" aluminum for the platform. Make sure you thermally isolate it from the plastic parts. Its really preference in the end, but i think 1/4" is best. Although thinner will make it easier for your steppers to move and will minimize backlash as well. You will have to choose your heating element as well. I am currently usiby CidVilas - Idaho RUG
Ive managed to take the Cocoa OSX Kinect application by fernLightning and add PLY export ability. I have tried many many different options available on the internet and this was the quickest way to get the Kinect connected with a computer. It took some figuring out to get the data to format right for Point Cloud file format, but anyway...its done now. I wanted to share in case there was intereby CidVilas - 3D Scanners, Book Scanners, and Optics
Just making an effort to resurrect this thread and hopefully get some QuickStart details from people who have gotten their kinect to work as a 3d scanner. @nrp: I tried your Python script but no matter what i do i get errors. First was that Python couldnt locate the Freenect module. Then it could not find some functions in the module. Could you help in getting python properly setup for Kinectby CidVilas - 3D Scanners, Book Scanners, and Optics
Has anyone been able to use RAMPS with Arduino 2560 and ReplicatorG? I have not been able to find a working combination with firmware where i can communicate with ReplicatorG. Also, why is Makerbot the only one using EEPROM memory to store system configuration like step count per millimeter and thermistor settings? Seems like this would be easier to store in the EEPROM and have these settingsby CidVilas - RAMPS Electronics
@CdnReprap: You could create a thermal loop. Attach a TEC onto copper pieces(for maximum thermal transfer) have one side attached to the heater barrel and the other to the insulator. So it will heat the nozzle and pull heat transferring into the insulator back into the nozzle. This is taking into account that TECs are really "heat pumps". Just an idea. See attached picture, and i apologizeby CidVilas - General
Be careful with the Peltiers. I bought a set of 5 which were max rated to 70C. I loved how it would heat pretty quickly. All of a sudden i couldnt get it to heat. It burned out on the 3rd use. Im sure there are more capable Peltiers out there, but considering the cost difference, it may not be worth it. Someone had mentioned to me that a Peltier may be an excellent heater/cooler if appliedby CidVilas - General
What i meant to say by "I missed that" is that i didn't quite understand why he attached the wires to NC (Normally Closed) instead of NO (Normally Open). This way, even if the switch comes undone or wires clip off, the switch will simply toggle as if tripped and the axis will not come slamming into the broken side. Its a safety feature. Most commercial machines are done this way as well.by CidVilas - General Mendel Topics
Oh! I missed that. So scratch attaching the wires to NO. Attach to NC and set ENDSTOPS_INVERTING = false;by CidVilas - General Mendel Topics
So my current electronic setup is Arduino MEGA 2560 with RAMPS (Probably V1) and Tonokip Firmware. I am wondering if anyone else experiances any connection problems with this. To connect to it using Repsnapper i must first apply the 12V supply and then connect the USB cable. If i upload a new firmware, i must again remove power and disconnect the USB cable and run through the power first thenby CidVilas - RAMPS Electronics
Just FYI: I tried mechanical end stops on my Mendel with RAMPS and Tonokip Firmware, and it works as described. I tied the Input to the COM pin of the switch and GND to the NO (Normally Open) pin of the switch. The following was added after the heater definition in the Setup() function, but before Serial configuration. pinMode(X_MIN_PIN, INPUT); // set pin to input digitalWriteby CidVilas - General Mendel Topics
@jgilmore: is this the case with all RepRap motherboards? Also what about debouncing? Will this effect the behavior of the end stop?by CidVilas - General Mendel Topics
What is your complete setup? What electronics are you using? What firmware? What do you mechanical switches look like? If you are running Tonokip, i beleive the end stops have to be defined in the code.by CidVilas - General Mendel Topics
Could everyone post there specs? I'm curious about Baud rate and Arduino Model. Arduino Model: Mega 2560 (RAMPS) Baud Rate: 115200 Firmware: Tonokip GCode Interface: RepSnapper Computer OS: Windows 7 Starter I have printed things with small and large round holes and have not experianced any slow down worthy of note.

Hello fellow RUGmeisters! I was just thinking that it would be a good idea to find out who, of the people who will attend the next meeting, is interested in buying printed parts. I don't think that anyone in the group has a printed kit available just yet, but i would be able to print kits by the next meeting. If you are interested please post here and specify what you would like. Going off oby CidVilas - Idaho RUG
Isnt the 26th RUG meeting?by CidVilas - Idaho RUG
I've sold both Makerbots. I can help print parts if interested.by CidVilas - Idaho RUG
Technically, the firmware wouldn't have to be rewritten. According to the documentation on Leaf Labs website, these boards in combination with their IDE can be programed with the same code just modifying pin assignments maybe. Slight mods may need to be made to Types and timing delays. Guessing as I haven't dug into the code yet.by CidVilas - Next Wave Electronics Working Group
Maple is a 32-bit processor running at 72Mhz. I wouldnt call it a replacement, but comparing it to the RAMPS setup, it would simply be a matter of availability when it came to price. The benefits of Maple is the huge amount of onboard resources available. You are no longer limited to the 16Mhz with the Arduino family and 72Mhz with Maple. So really comparing the list below, Arduino Mega 2560by CidVilas - Next Wave Electronics Working Group
Sacrificing the pins for SD card and maybe even a Key pad, you could easily add 6 steppers (3 pin per Pololu), 4 Thermistor (3 Heads Plus heated bed), 4 Heater MosFets, and some other minimum requirements like endstops and leds.by CidVilas - Next Wave Electronics Working Group
Just a heads up for those that may be interested. I have two Makerbot Cupcakes and a Green Mendel i am looking to part with. I have an idea of the price i am willing to sell them for, but i am willing to take offers. I hope you guys don't mind me advertising here, but i figure since its a local group looking to get going in this hobby that it might be the perfect place.

In case anyone wants something to work off of. Heres a template of the board layout.by CidVilas - Next Wave Electronics Working Group
Sorry for the late response. Thank you all for the information. I am still looking to getting this moving, atleast for myself. I will definately make an effort to document and share my findings, but i am no expert. Is anyone interested in getting a circuit drawn up? I would be willing to pay for your board to be made. This should be a shield for "The Maple" board. This board is tiny so i'mby CidVilas - Next Wave Electronics Working Group
Yessir! I am officially a Reprap Mendel Technician. Maybe i will bring her in for the next meeting. Im open to either date.by CidVilas - Idaho RUG
This is true. I beleive that you can get ~140mm without anything mounted on the carriage. To maximize your build height, you would probably want to move towards an Bowden Extruder setup like you find on a Ultimaker (http://blog.ultimaker.com/) This way you do not limit the Z height by the extruder height. I am using a Stepper Extruder from Makergear (http://www.Makergear.com/) and i am able toby CidVilas - General Mendel Topics
Located in Boise, ID. This will be my second Mendel being built, but it will be my first built to completion. I look forward to producing at least 5 Mendel kits. Flickr Page for Cid Vilasby CidVilas - Idaho RUG
If you take multiple views i think that it would be higher. You would have to sweep an object from specific angles and then use some 3d mesh repair software to combine them all. I believe MeshLab does this.by CidVilas - 3D Scanners, Book Scanners, and Optics
Hey all! I just caught this video and thought to myself "This is the perfect cheap 3D scanning option! As you can see in the link below, people have managed to connect to the device and reconstruct what it sees as 3D objects. By meshing multiple views, we can recreate full 3d objects.
