I have a CNC mill that I was running on RAMPS 1.4/Marlin for about a year with very good success. I ended up making a new 3d printer and stole the electronics from the CNC for it and purchased new pibot electronics for the CNC because I liked the driver rating that came with them. Pibot was made for repetier firmware so I transferred all of my Marlin config settings over and got things running prby tkole - Firmware - mainstream and related support
I've run marlin on my cnc for about a year now using cambam for my CAM operations and a plugin for marlin with no issues.by tkole - General
QuoteMrDoctorDIV Acceleration, while allowing higher speeds, lowers the quality of your corners. Agreed. The question is really what is better, high acceleration and lower speed or low acceleration and higher speed? In terms of print quality I see a huge, positive difference, when I print with my acceleration in the 9000 mm/s2 range. As doc said, the quality of corners and holes on vertical faceby tkole - General
Thanks cnc dick. I'm thinking of changing to 1.75 mm filament anyway... Dejay, my extrusions are 500 mm long so I'm not sure how something 1m or longer will behave. As for a tensioner, here is mine. A very sophisticated cable tie.by tkole - CoreXY Machines
Dejay, I don't have a thread or build blog, but here are some pics below. The black extrusion is vslot and the silver extrusion is from Misumi. You will notice my E3D heat block dangling in one photo because I am currently fixing a broken piece. cnc dick, you are correct. My hotend can't extrude fast enough. I have tried mk7 and mk8 direct drive as well as a geared wade's for my Bowden setup butby tkole - CoreXY Machines
QuoteDejay Sorry for going a bit off topic here, I hope you won't mind I'd like to build (or actually I would like to have ) a printer with a really large print volume. Something like a 600 to 1000mm cube print volume. And it should be able to carry a dual direct extruder, or rather a quad extruder that can directly feed something like the kraken but with only 2 steppers.

Where do you get your lead/ball screws?by tkole - General
It's not so much for the hole as it is for the inertia check. You can unmask many acceleration issues by throwing a hole in the path of a vertical wall. With the mass of your xcarriage and bed, I imagine printing this piece would be very telling. I'm not sure why PLA vs. ABS has anything to do with the discussion.by tkole - General
Now that is a nice test piece. That allows you to see layer alignment, inertial effects, etc. Nice job doc! What did you use for speed, accel, and jerk for that print?by tkole - General
The yoda is definitely nice, but these objects don't give a good measure of a printer's capability in my opinion. I want to see an object with flat vertical faces and sharp corners. All of the curves and irregular borders mask the limitations of the printer.by tkole - General
cnc dick, can you post a link to the serrated drive wheel that you use?by tkole - General
I ended up getting it to work. I'm not sure why this worked but it did. #define EXTRUDER_FAN_COOL_TEMP 0 I dropped the temp from 50 to 0. I thought this would just leave the router on all the time and was trying it out as a test. It ended up giving me full m106/m107 control.by tkole - Repetier
I just bought a Pibot electronics kit to try out for my CNC router and am having a slight issue. I was able to upload the firmware, connect to repetier host, and home and move the axes of my machine. The problem I'm having is with control of the fan port which I use to switch on/off an SSR that is connected to my router. When I turn on my 24V supply to the pibot board, the router powers on for abby tkole - Repetier
Protoparadigm or newimageplastics. Newimageplastics only sells in 10lb spool minimums though.by tkole - General
There are settings in some slicing programs (like slic3r) that can do this. Just look under the retraction settings.by tkole - General
Quotethejollygrimreapernice , however those are considered to be higher end brands of filament so no surprises there, I agree with protoparadigm and ultmachine being highend but I wouldn't consider Jet in the same category. $29 shipped if you have amazon prime and it usually arrives in 1 to 2 days. It's not my primary brand but it helps when you are in a pinch. No offense Jet, whoever you are.by tkole - General
Quoteohioplastics It's about efficiency and cost effectiveness. People shouldn't have to pay $80 for an all stainless steel hot end when all you really need is 1" of M6 rod. It's a $2 part. And a several thousand dollar laithe. If I had one of those I would make my own hotend.by tkole - General
Quotethejollygrimreaper "PLA works beautifully with it" is something i hear quite often ,but which brands/color/size? not all PLA filament is created equal at the same time Protoparadigm (black, red, orange, silver, forest green), Ultmachine (orange, black, red), Jet (black, red, orange, silver). All 3mm diameter with 0.4 mm nozzle diameter. Printer is running around 12 hours per day without aby tkole - General
Quotethejollygrimreaperto me it comes down the the right tool for the job, "an extrude it all" hotend is a bit of fantasy at this point in time however in the future when the industry demands much tighter quality control over the filament then it might be worth looking at again, until then people really should start getting used to the idea of having multiple hotends for different materials I'mby tkole - General

There are others available but that one looks good. I use this one from mcmaster that runs off of AC using an SSR hooked up to my electronics. There is a link to the silicone adhesive there as well. I just mounted mine beneath a sheet of aluminum. silicone heatpadby tkole - General
I am using a 1/16" thick piece so it's not a film. I crashed my nozzle into it at 225C accidentally and it didn't scratch. It seems like it will hold up quite well, which is the reason I tried it in the first place. I hate peeling off and reapplying Kapton. You can buy this in a film as well but I think you would end up having the same problems as Kapton then.by tkole - General
I'm not sure if this has been brought up before but I thought I should post my results of using Ultem PEI as a printbed surface. I bought a piece of 12x12x1/16" Ultem PEI from McMaster-Carr and then attached to my aluminum printbed with 12 bulldog clips (3 on each side). I then tested it with PLA and ABS. My first run was with PLA at a bed temp of 55C (measured with a thermistor attached to thby tkole - General
I am running a RAMBO board and want to implement the bed leveling features in the latest Marlin using a servo to lower/raise the bed probe. I know that RAMPS has connections available for a servo. Does anyone know if this is possible with RAMBO? If so, where?by tkole - RAMPS Electronics
Just to throw my 2 cents in, I recently built a 2' x 3' CNC mill running NEMA 23's at 330 oz-in a piece. I have 2 running my y-axis, and 1 on each of my x and z axes. I use RAMPS 1.4 running the latest Marlin firmware with panucatt SD8825 drivers and pronterface for control. Initially, things were a bit slow but when I changed to a 24V powersupply, I running smoothly. I have milled wood, aluminumby tkole - General
Glenn, one piece of 80x20 should be fine but it depends on the dimensions of your bed plate. I had 1m of the stuff sitting around and only needed 450mm so I figured, might as well use two pieces and make it that much stiffer. Sorry for not posting pics, I got side tracked. I will make a reminder to do this when I get home tonight.by tkole - Extruded Aluminum Frames
No issues at all. Over the last couple of months I did upgrade my z-axis screws to trapezoidal lead screws and beefed up the y-axis rail with 2 pieces of 80x20 v-slot. It's rock solid now. I'll post some updated pics later.by tkole - Extruded Aluminum Frames
