Hi Selling Mendel. Built from parts printed by Nophead. Stainless hardware, Heated bed Collect only Located in Lyme Regisby emt - For Sale
Hi I have a Reprap I built a number of years ago from printed parts supplied by Nophead that I want to sell. Is there any where on the forum I can offer it? I don't want to ruffle feathers!by emt - General

Many thanks. I will study the PCB info and investigate the MendelMax heater.by emt - Controllers
I have now added insulation below the PCB and the duty cycle is now about 30% on when the bed temperature stabilizes. It takes much longer than I realised to stabilize so the earlier readings I gave were incorrect. I am also measuring the current with an ancient clip on ammeter which may not be accurate. I don't have an in circuit ammeter that goes above 10 amps. I am also using an aluminium plby emt - Controllers
Hi I am using a Prusa PCB heated bed. I am setting up my Mendel to run on solar power (24volt batteries). The first step was to switch the heated bed. I am using the Ramps output to drive a 30amp relay and the system works. However the bed draws around 13 amps and is causing voltage drop on the 24v volts which also runs a lot of my IT equipment. The relay duty cycle is about 80% on. I would liby emt - Controllers
Many thanks again Frédéric. That worked like a charm.by emt - Slic3r
Frédéric Many thanks. That taught me a bit more about EMC2. How would you modify gcode2ngc.py to also replace all S with P? I tried to guess the solution and ended up with duplicate lines. Also the other line that causes me a syntax error in EMC gcode is the M82 generated by slic3r. At the moment I am editing the Gcode file and deleting it. How do you deal with that?by emt - Slic3r
Many thanks. I did miss that. Is there an easy way to change the g code file suffix?by emt - Slic3r
Hi I am keen to try Slic3r. I use EMC as control software so I us A instead of E for the extruder. I can use global edit in an editor to make changes but that can be time consuming. My experience of Linux is limited, can any one point me to a quicker way? Ideally a means of converting a number of files at once.by emt - Slic3r
Hi I use brendanjerwin's method with great success. One issue you might face is homing with a cold extruder with plastic on it, IF you home towards the bed which I find most convenient as the Z axis is so slow. With my set up I issue heat commands from a terminal window so the plastic is soft when homing. Also are there enough pins available to run a heated bed as well as the extruder? I found Iby emt - EMC2
Hi Ahmetcemturan I noticed in the latest changes text file you state you have commented out chamber temperature. I personally use this. If you start building very big parts you end up putting your reprap in a case to get even temperatures. This helps to prevent corners warping. Could this be re instated?by emt - Skeinforge

Many thanks. My set up is unusual. I use EMC with Mendel. My background is CNC and I prefer the total machine control EMC provides. In the home file I issue an optional stop command and sometimes a bed heat reduction command. This means I can stop between layers if I want to. This enables all kinds of actions. Embedding nuts. Putting in prefabricated supports. I have also started a job, had to gby emt - Skeinforge
Hi I have tried SFACT with excellent results. However I would like to be able to use the HOME plugin. Having copied the plugin which file do I alter to add it back to the Craft menu?by emt - Skeinforge

*I am not getting any feed on the first layer now though since setting the Restart extra distance to -0.2.* Are you using skirt? Set to 1 layer it will move any problems off the job and the first job layer should be OK. If not careful use of initial splodge may help. Set operating splodge length to 0 to avoid it working on other layers.by emt - Skeinforge
You can set restart extra distance in Dimension to a negative number. This means less filament is fed at the start of each layer.by emt - Skeinforge
Hi I do have multiple replace files. Mainly due to different materials at the moment. But shortly different material diameters and different nozzle sizes as well.by emt - Skeinforge
Hi James Really useful - thanks. Note the latest version alterations directory is in the skeinforge_application directory. Could you add that to the backup?by emt - Skeinforge
