Re: Marlin not Compiling for Sanguino(lolu) - 10 years ago
Solved .. Each time I decide to update to the latest version it takes a considerable time to get the compile enviroment correct even when you follow all of the instructions and notes supplied with the release...

Marlin not Compiling for Sanguino(lolu) - 10 years ago
So far the problems seem to be with some confusion over the header files Arduino.h, WProgram.h, Pins when compiling with the Z servo option set Both Midge and myself have been looking at these problems for a while now..

Re: 1.8 deg/step vs 0.9 deg/step - noticable difference? - 12 years ago
Wild Bill, I use 0.9 steppers and 14 tooth XML pulleys on X and Y and E on Huxley seedling using Sprinter or Marlin firmware on a standard 16mhz CPU. I'm intrigued as to why I would need to use an ARM CPU as both versions of Firmware running @16mhz on Huxley seedling easily exceed the maximum step rate for the stepper motors at 16x stepping at fast positioning rates jog & fast moves as extruby BodgeIt - Mechanics
Re: Sanguinololu prints of pcb come out wrong Can't etch eagle help - 12 years ago
The main problem with Eagle and making a PCB from the printer output is scaling you need to rescale every board to print as a PDF to do laser transfer. so print the file measure it in X and Y to get the right layers showing use display hide layers as Nophead said. Now measure the length calculate a factor to correct the print for both X and Y the reprint and re-check you can hen save it as a PDby BodgeIt - Sanguino(lolu)
Re: Air filtering for Laser cutters a big must have - 12 years ago
The Laser cutter I have is an old Universal before Airasist was fitted as standard so when it was installed the guy adjusted the Filter suction to remove flame out when cutting 10mm perspex. hence the filter is not far off its maximum suction.

Re: need clarification on Sanguinololu and motors - 13 years ago
The Sanguinololu connections are the same as your current driver board >> A A- B B- Do remember to set up the current on your Pololu boards to 0.4 v on the wiper of the Pololu pot. Note: you can set up the Pololu pot voltage with out having the main motor supply (12v) connected when the Sanguinololu is just being powered by its USB connection. This is the safest way to set the Pololu boarby BodgeIt - Sanguino(lolu)

Re: HOW to stick ABS and nonheated table? - 13 years ago
A 10mm thick perspex print bed works very well with ABS. You must not print PLA direcly onto the perspex bed as it bonds too well. So for printing PLA on a perspex bed you must stick Blue painters tape onto the perspex bed first.by BodgeIt - Plastic Extruder Working Group

Re: The Phoenix Project: Recycled Epson Printer Parts into 3D Printer - 13 years ago
Not all printers use two steper motors now days. It is usualy only one stepper motor to run the paper feed this is usualy a 7.5 degree step not a 1.8 dgree step as used by reprap. The print head is usualy a servo type system based on a standard motor with an optical feed back sensor to get very high speed print head movement and resolution at very low cost. So using a 7.5 degree stepper ie 48 stby BodgeIt - General New Machines Topics
Re: Blew up a Pololu last night... - 13 years ago
On all versions of the various Pololu type stepper controlers when used on a Ramps type board you can adjust the curent setting without the 12v -24v main motor/heater power suply being turned on. I have found the easiest way to do this is to use a small metal instument screw driver that has the red wire of your meter conected to it while the black wire of the meter is connected to the 0V of theby BodgeIt - RAMPS Electronics
