Re: Generation 7 Electronics Development - 13 years ago
I learnt how to design a Laser able Gen 7 box yesterday in my new Fablab at Home office (aka Hallway) these are as yet untested as I have not built the boards yet.. slip up with connectors I assumed 5.08 pitch pins they are slightly different so may just use vero pins to chocolate blocks if i can find the vero pins. Any way here's is a preview of the Gen 7 box.. Midge is more Geeky than me asby BodgeIt - Next Wave Electronics Working Group
Re: Why Brass? - 13 years ago
They are marked 0.6mm but are atualy are 0.75 as 0.6mm welding wire needs some clearance not seen smaller other than some one sqished the end amd re drilled or solder with high temp solder like nophead did and drill.. The 0.6mm welding tip is good enough to make Draft parts test the system the extrusion is around 0.85mm to 1mm extrudate.by BodgeIt - Plastic Extruder Working Group
Re: Plastic recycler - 13 years ago
That looks like the machine the Makerbot group coppied to recycle their ABS posted some where in the forum .. or in the WIKI The one they show is a much bigger version as it is shown eating shopping trolleys. They show details of the teeth and the seperator plates in their blog..by BodgeIt - General
Re: Generation 7 Electronics Development - 13 years ago
Percived problem areas for home etching however on taking close ups with a camera its very marginal so it may not be too bad. Maybe just a tiny smidgen of extra clearance. Just drilled out two boards to 0.6mm holes will now try and figure out the ones that need to be bigger next.

Re: Use Continuous Servo as extruder filament feeder HELP! - 13 years ago
The print axis on all standard ink jet printers are direct servo drive mechanisms all using DC motors with optical positional feedback. So speed is not a problem just the optical encoder strip and reader device in DIY quantitys creation of the software to controll the sevo. Most printers seem to be Arm processor based as well.by BodgeIt - Reprappers

Mark will do I will mark them up on a pdf The strangest of strange things is that the parts that needed touching up on both transfers were almost exactly the same parts.. will take a pic.. now both were printed on one sheet at the same time included the two up PDF Its very strange I can not think of a reasonable explanation as to why transfer has not happened in the same places the bare PCB usby BodgeIt - Next Wave Electronics Working Group
Re: Generation 7 Electronics Development - 13 years ago
Using Maplin PCB transfer film as I have run out of the right sort of pound shop label backing this laser transfer method is about 4 x more expensive @ £16.99 for a pack of 5 sheets. Most effect way to use clean board with nail varish remover do not pre-heat as per offical instructions just Iorn on for 5 min let it cool for two min then run under cold water peel inspect touch up with water proofby BodgeIt - Next Wave Electronics Working Group
Re: Idea: Aluminium Oxide PCBs and Redox - 13 years ago
Aluminum soldering is similar to Aluminum welding it requires a slightly diffrent flux you can use standard solder with not so good results. I sure I'v seen some recently I think it may have been Maplin.by BodgeIt - General
Re: Generation 7 Electronics Development - 13 years ago
Thank you Mark .... What is an overlapping error.. is it like you had to do in the days of blue red tape or even black tape where you had to overlap all the track tape joins to stop light going thru.. ? Would you mind making another PDF with the alterd lay out? I need to use the wallwart variet as I only run on 24-30v Single supplies don't use PC PSUs even though I have loads.. of them..

neonek911 Thank you for that Gen7_ICSP.ps file Unfotunatly using adobe to read or translate it to PDF the PCB image is printed 10mm too high for A4 paper. So I nstalled Gimp 2 for Windows unfotunatly the Windows version of Gimp2 has not got the file Ghostscript. When you say maximum resolution do you mean all the 9s in the top feild of pic2 ?

Re: Use Continuous Servo as extruder filament feeder HELP! - 13 years ago
There is servo control built into the Arduino examples that can be used with standard RC servos it works just fine. The servo support is for the common Radio control type servo. They uses a potentiometer for positional feed back thus these types of servos have a limited movment. On instructables there are at least two items were the pot is removed and the stop on the gears removed then a multiby BodgeIt - Reprappers

Re: Motherboard Power Alternative - 13 years ago
My point was from my experience you don't need to run them with a 1A driver setting per winding; in the first place let alone 2A per winding. I think setting these very high coil curents could be why there are somany Pololu drivers being cooked/blown up. I am still using the old stepper drivers I will be trying out Pololu drivers soon. So I may have to increas the current slightly to accomodateby BodgeIt - Controllers
Re: Resetable fuse alternative product? - 13 years ago
Its a pity the responce time is 14.5 seconds some thing a lot faster would be ideal to protect over current on Pololu drivers. I see so many reports of blown up Pololu drivers in the forum.by BodgeIt - RAMPS Electronics
Re: Generation 7 Electronics Development - 13 years ago
I have the Print driver for my HP LaserJet 2100 PCL6 set to 1:1. Printing with scale set to 1:1 works fine with PDF files, Direct prints from Kicad, Direct prints from Solid Edge 2D drafting ST3 Not working If using with Eagle even with Eagle scale set to 1:1 the final print is out by a diffrent factor depending on the board size used in a design. So you need to measure the print in X and Yby BodgeIt - Next Wave Electronics Working Group

Re: Generation 7 Electronics Development - 13 years ago
Both versions are looking very good ! I think the Eagle version stands a better chance of Iorn on transfer as all the signal lines are a little thicker. Great work is there any chance of a 1:1 scale PDF file for Iorn on Etching? I usualy use Kikad as its open source and compared to Eagle when you print to a lazer printer it is printed to scale. On Eagle its a right pain printing measuring anby BodgeIt - Next Wave Electronics Working Group

Sorry, I also used to live near Ashford in Kent too. I'm now 240 miles north west of you. I have seen many new problems here that I remember seeing an answer for in the forum threads, but try as hard as i can I cant re-locate the thread.

Re: Standard Interface for Extruders - 13 years ago
All of these links make it two connections at the extruder... what is wrong with directly soldering to a standard bucket DB9 connector? I like the Idea of having a standard plug in connection.>< DB9 is well proven standard. I think its still quite a bulky connector for hanging off the extruder there must be some thing better that could be used. Maybe spade connectors or bullet connectby BodgeIt - Plastic Extruder Working Group
