Thanks, Had trouble reading the other day, by the time i was looking for that, and missed that line. Im meeting up with the other South London Makerspace members tonight at our temporary weekly meet up. So have a chance to swap some notes and get opinions on what ive done so far. Thanks Gordonby gordonendersby - Reprappers
Ive done all the motherboard, thermister, end stop stuff and its all working fine as i said in my post. I can home all the axis and level the bed. I can extrude filament at the right temperature. Ive got my software chain sorted, finally. Pronterface, skeinforge. Ive done a dry print with everything moving as expected. As far as i can see i just need to set the steps per mm for xyz and the extrudby gordonendersby - Reprappers
Ive built a prusa mendel i2 from parts not a kit and got all the mechanics and electronics working and talking to pronterface. Everything now moves, heats and homes nicely. This is probably a bit silly to ask. You will have to forgive me im a bit brain frazzled today after sorting out the prontiface and skeinforge on linux. Had some problems as i had a lot of fun sorting through all the differenby gordonendersby - Reprappers
Looks prettier like that doesnt it. I didnt want to swap it round as it just looked wrong having one set reversed. Just before i turned everything off i tried it again for sanity via the lcd control. Guess what, it went up instead of down when i selected home. But id being fiddling with the plugs again so it may be a loose connection in the plug. I dont like those pin connections they should beby gordonendersby - Reprappers
Ive only gone and sorted it!. Thanks for all the help it gave me the inspiration and clues to solve it. As expexcted something silly, but non intuitive. Id set invert_z-dir to true as my z was going up rather than down. Even though the comments said for mendel set to false. What i should have done is turn the plugs around on the ramps board to compensate. But because all my other pins were theby gordonendersby - Reprappers
I can wind it down by hand and that is then z=0 when i turn the machine on. So yes i can manually set the home position. Just tried setting the position of the z axis just above z=0. Z=8. With the z axis just above the switch. Then gave the home command via the lcd. So it should have moved as far a before down the z axis. But it still stopped when z=0 and didnt reach the switch. So doesnt look lby gordonendersby - Reprappers
Thanks for the comments. Sprocket1597, I wonder if the motor is turning and reaching the maximum number of steps and stopping before it gets to the switch? I havnt yet done any of the fine tuning to set the distance to steps. Thsts my next job after i get home set for all axis. Ill look into that. Ive tested all end stops and they are all working. Also ive twisted the end stop wires, but alsoby gordonendersby - Reprappers
Ok, tried some more. Got hold of the latest marlin from github. In case there wad something wrong with the copy i got wih my ramps stuff. Set it up and loaded it. No change. Still cant get the z axis to go down to the z end stop. Pretty much stumped now. Any help? Gordonby gordonendersby - Reprappers
Had a go again today with clear head. Long day yesterday. I tried setting min_software_enstops = false All this does is allow me to go past the end stop while i command the axis to move either through pronteface or the lcd menue. Homeing the z axis will still not let the z-axis reach the z end stop. Next tried reversing the endstop so that it would look for a stop at the top of travel. This timby gordonendersby - Reprappers
Hi guys, Im building a prusa 2 from scratch, no kit, just by reading the guides on reprap.org and the bill of materials. Sourced parts from all over at a fair price and cheaper than mostof the kits. Everything has gone fairly well. Im using Marlin with ramps 1.4. Ive got everything up and running with motors moving, bed and hot end heating. Lcd display and controls are responding and controlledby gordonendersby - Reprappers
Not exactly essex, but have you looked up the London hackspace in the east end of London E2. They have a 3d printer group there. We have a burgoning 3d print group at the south london makerspace as well. But no where near you. Or you could see if there are any other hackerspaces/makerspaces nearer to you. They are starting to pop up all over the country. Gordonby gordonendersby - General
That got through, lets try again. Thanks for the confirmation on the directory with the files. Ill package them up and pass them on. Yes, ive found loads of documentation and video on the build. Thats why i chose this printer. As well as the fact that its a good base for many other versions and improvements. Im not always good at documenting my projects but ill have a go here: **This would havby gordonendersby - General Mendel Topics

Hi, First time poster but ive been reading up a lot from the forum and the wiki. Loads of good information for the first timer if you have pacience. I need a small bit of help. Im making a Prusa I2 ive sourced a lot of the parts and a friend from South London Makerspace is going to print the plastics for me. Im using the lm8uu linear bearings and sticking to the wades extruder. Im building itby gordonendersby - General Mendel Topics
