I was in the same boat, also. You may find other posts on this topic made by me... I've lost track of many of them. The TechZone Huxley used 6mm and 1/4" parts. The smooth rods were 1/4", and modern bearings for 1/4" components are 4x-6x more expensive than those for 6mm smooth rod. The TZ Huxley used skate bearing arrays, obsolete at the time it was sold. If you replace the 1/4" smooth rodby Phuzzy Logic - Huxley
RTurnock- Thank you for the prompt reply. The PLA I received from PrintrBot was the clear translucent variety. Sorry to hear about the complications from the mismatched extruder parts. I have the direct-drive extruder, V2, July edition. It works well. I am reading about the Prusa I3 and mixed-up my terminology. You may be running hot. I get good results at 185 deg C. I have read that filby Phuzzy Logic - Delta Machines
RTurnock- I read your question, and hope that you might make it more clear: 1) Are you printing with a copy of the 3DR Simple Delta? 2) Are you printing with a PrintrBot Simple? 3) Are you printing with a Printrbot compact extruder? 4) Are you printing with a Bowden-tube filament feeder? 5) Which filament are you printing with, PLA, ABS, or another filament?by Phuzzy Logic - Delta Machines
Techzone went out of business. Their laser cut Mendel is documented by several links on the following page: "http://reprap.org/wiki/TechZone_InfoHub" . Some of the links document lists of materials. Techzone included a printed BOM (Bill Of Materials) with my Huxley kit. But, although I received all the parts listed, it was not enough to complete the assembly. -Phuzzyby Phuzzy Logic - General Mendel Topics
slice396- This is the same question asked by roady001 in a recent thread ). As far as I know, a 12V 20A power supply would be sufficient. Your power supply is likely maxing out and shutting down on a safety switch. The higher amperage will require attention to the wiring when connecting the power supply to the controller board. Plugs and sockets for laptop bricks must match; and 12V dedicby Phuzzy Logic - Huxley
Stevestorr - You are likely talking about the "Frog Piece", so named because it resembles a squashed frog. It may differ according to the variation of the Huxley that you intend to build. Look in the repository for the particular set of parts that you have assembled. One variation, for the TechZone Huxley, can be found under the "Files" heading on the TechZone wiki page (http://reprap.org/wikby Phuzzy Logic - Huxley
roady - In your original question, you asked if 6A was enough, and I am saying that it most likely is not enough. You may have damaged your power supply by overloading it. -Phuzzyby Phuzzy Logic - Huxley
roady - Your power supply at 19V and 6A is about 114W (watts) capacity: Wattage equals Volts times Amps (W=V*A). Sometimes you will see a power supply rated at "VA" rather than "W", because the terminology is equivalent. That being said, I am assuming that you are printing PLA, which does not require a heated bed. You could likely print PLA all day with the heated bed set at 0 degrees (off)by Phuzzy Logic - Huxley
I also ordered from 3DLabtek, after reading through the original two posts. The owner asks for e-mail communication prior to an order. I complied, and ordered, and received my order promptly. It took less than two weeks total to arrive in the USA from Poland. I ordered the all-metal i3 x-carriage and plan to use it with an i3 build in the near future. It should work well with an all-metal hiby Phuzzy Logic - General Mendel Topics
Maxi- The fins exhibit greater surface area per the mass of aluminum. Greater surface area allows for better heat dissipation. The fins will work better. Will the rods be enough? Proper adjustment of the trim pots is sometimes enough to do the job without heatsinks. -Phuzzyby Phuzzy Logic - General Mendel Topics
StephS- Thank you for your response. Is there a documentation page where I can find information regarding the jumper settings? I found that each set of 3 jumpers on my board is shorted completely (I am assuming 3 x high). If these jumpers control the step resolution settings, then they should produce 1/16th stepping with an A4988 board and 1/32 stepping with a DRV8825 board. Please correctby Phuzzy Logic - General Mendel Topics
StephS- I also have a problem with the TeensyLu. I purchased 4 DRV8825 Pololu boards, and they will do 1/32 stepping. On other boards, such as the Gen7 by Traumflug, you set the stepping level with jumpers. I do not see any jumper pins on the TeensyLu, and I need a clue as to how to set the stepping level. I hope that I am not "hijacking" this thread, as the topic is the TeensyLu. Apologiesby Phuzzy Logic - General Mendel Topics
JamesRX- Printrbot ships their Simple printer with a lightweight laptop power supply. To print ABS, you have to use an ATX power supply. A 400-500 watt ATX supply should be enough. If you have an old computer, you can pull out the power supply (486 or later model). Or, you can spend $15-$50 dollars on the web for a new-in-box model. I think your laptop model PSU is about 120 watts. The conby Phuzzy Logic - General
How powerful is your power supply? Have you tried swapping it out with an ATX (or similar) computer power supply? The stock Power Supply Unit (PSU) may not have sufficient wattage to do the job. Other printers are sold as "PLA only" unless you add your own, larger, ATX-type PSU. Personally, I was fascinated by the Portabee design and the high-quality documentation provided. I hope you find tby Phuzzy Logic - General

George1- What flavor of Huxley do you have? There are several brands. What type of extruder? What temperature are you using to print? Are you using a heated bed? Please add a few details. -Phuzzyby Phuzzy Logic - Huxley
gmerz- I would reason that the mixing nozzle would clog. Any power outage, or any hesitation on the part of the printhead, would allow the 2-component mix to solidify. If the resolution is to be as high as an ink jet, the viscosity of the mix must be extremely low in the nozzle, and then harden rapidly after deposition. The nozzle size may be at least an order of magnitude less than the nozby Phuzzy Logic - General
Jojo- My suggestion is to use modern electronics. TZH monolithics failed frequently, and they are limited to half-stepping and to older softwares. The original hot-end on the TZ Huxley consistently fails, also. I am redesigning my Huxley around available off-the-shelf components. The Bowden Tube and gear set can be used with a modern J-head, and requires only a simple X-carriage mod (DeuxVby Phuzzy Logic - Huxley
Jojo- I read your most recent post in the Huxley forum, and then looked at your older stuff (including this old post). I gave up on the TZ design, and am deriving my own from the kit and more modern components. I was able to purchase a gen7 electronics kit (it will do microstepping) from Traumflug, and an extruder kit from SeeMeCNC (it can use either 1.75mm or 3.0mm filament), both for less tby Phuzzy Logic - General

KD0SKH - I have an unused TZ Huxley monotronics board if you really want it. It has never been out of the box except too look at it, then to put it back. That said, I have never tried to hook it up. My intent is to use Gen 7 electronics from the start, along with a conversion to 6mm smooth rods, LM6UU bearings, and an X-carriage modified to use LM6UU bearings (see "http://www.thingiverse.com/by Phuzzy Logic - Huxley
