Quoteregpye Using the old power supplies we use to add a load resistor between the green wire and a black one, that held the power supply in the "on mode" You should be able to do it by connecting the green wire from the power supply to the pin on the RAMPS that does the automatic turn on and off. That pin is next to the reset button, the closest on the left when the reset button is facing you.by djinn5150 - Smart_Rap
Yes its definitely an old PSU, I had added some led's to the 5v rail in hopes it would alleviate the problem, but I was not so lucky. I think today Will try powering the Arduino off it and see if that is enough draw to keep it alive. Going to need to do that anyway if I want to upgrade to a stand-alone at some point.by djinn5150 - Smart_Rap
QuoteMelT I better find a way to put that sticker somewhere in my machine. Maybe I will 3d print it and put it in the support between the two z-rods Now you got me thinking, I was planning on expanding the y-axis out and turning the print bed 90 degrees and having the sticker on the underside. Now I'm thinking I might be able to model that up in sketch up and print it up as a z-spreader/supby djinn5150 - Smart_Rap
Quotemadmike8 Looks good. Are you looking at the same picture I am? Its a mess lol It will come around in time, now that I have a feel for whats going on and what I "need" etc. In all seriousness, thank you! There will be many more changes down the line.by djinn5150 - Smart_Rap
Well it is definately far from "done" but its together and working fairly well at the moment. Thanks again to everyone that has helped me out in my journey here. This is in its current state. Things I have still to do. Clean Up wiring Finish "Regpye's Extruder" and get it mounted Develop a 5 volt load for my PSU( it wont stay on unless I keep the CD drive hooked up) Clean Up wiring!!

Awesome I will for sure have a look, maybe I'll just go that way instead of the this Wades I printed out, can't hurt to have extra parts laying around. I do like your's and its "add-on" style to the Smartrap, maybe I'll give it a go now things are running so smooth. Any tips on learning CAD on the side. I never have had any experience in it at all. I have been able to make a few things in skeby djinn5150 - Smart_Rap
Quoteregpye Looking good now. Pays to stay with it for a while, the problems are very good, it makes you learn something. If you had just bought it ready to print out of the box you would not appreciate the machine as much. Isn't that the truth, and honestly I think most of my problems were in my inexperience in setting up slicer and impatience, at least for my build 30mm/s is just to fast forby djinn5150 - Smart_Rap
Well looks like I got most of my issues settled out, at least for now. I have had several successful prints at this point and will be changing to a Wades extruder not to far into the future. But for now it seems to be working quite well. Once I get a few brackets printed I will get my "build" finalized and start a new thread with some photos.by djinn5150 - Smart_Rap
My best guess would be the NoServo version found in the github, youll need to adjust your steps to match up with the belt drive system. As to what those numbers would be someone else will have to chime in. Looks good, at some point I would like to move up to belts or the new rack system, so I'll be watchingby djinn5150 - Smart_Rap
So how much failure should a noob expect? I am getting very frustrated with this, and while my ego will not let it beat me I am getting very frustrated and doubting everything at this point. I just don't get how I can have a beautiful print one second then try something else and it just fails miserably. I know I am having extrusion/feed issues that I can't seem to wrap my head around, my PLby djinn5150 - Smart_Rap
Quoteregpye Quotedjinn5150 So I got some of my issues worked out but I have been trying everything to diagnose this problem for a while now. Time to post a video and ask the experts. Basically what is going on is Z axis will travel properly if I send a travel command in repetier host in both the + - directions. Once I send a home all axis or a g30 it basically doesn't move like its binding up.by djinn5150 - Smart_Rap

Yeah I was thinking that too but Have triple checked everything, now I have another strange behaviour, while im still having some issues with x/y randomly my Z seems to work as it should until I send a g30 command, it will go down about 1-2 mm then up then back down then stops, if I send say + 10 it will start to go up then sound like a jet engine reving up (stopped) then it will go up a bit agaiby djinn5150 - Smart_Rap
I think my Ramps board or stepper drivers are going bad/gone bad something, or could be PSU. Its acting really weird now, sometimes an axis(happens on all) will not respond to command, or if it does...say I send x + 10 from pronterface x will move in + then I send again it moves in - At first I thought It was maybe firmware so I tried loading sprinter and almost same thing happens not sure wheby djinn5150 - Smart_Rap
Quotemarkstephen That's looking better. Looks like the feed slowed a bit in spots, but is definitely an improvement. Here are a couple of prints I did last night, Jack Blocks (step blocks) and Hold Downs for my CNC router. I was at the very limit for my text size on this one.

I think I found the sweet spot for the z offset, I'll give Cura another shot, I don't remember adding any offset in the Gcode but as frustrated as I was getting who knows. Maybee I'll give it another shot in the next few days. Definitely headed in the right direction though, did these last night.by djinn5150 - Smart_Rap
I tried Cura and got 1 good print out of it, I really like the simplicity of the interface but for some reason It seems I need to calibrate the z-offset almost every print, and since the 1st print with cura I cannot get it to actually lay anything down on the bed, its always just a smidge too high for some reason and nothing sticks. I'll figure it out someday. On another note I did get my littlby djinn5150 - Smart_Rap
So much knowledge...thanks again guys I'll hunt down a M5 and shoot for INOX. Things are going ok now, If i can get my strings and circle problems under control I will be a happy camper for a while. Circles are consistently undersized and I have yet to understand why. Everything else in the model is x/y wise is spot on Z is off but we already know why I am having problems there. Thank you agaiby djinn5150 - Smart_Rap
Awesome tips regpye, thanks. Those are some beautiful prints there, Hopefully one day I'll have mine dialed in enough to print parts for a mendel of some sorts. It's still giving me issues but I am almost certain its user error and slic3r settings more then anything. I am not using a m5 sadly they are hard to come by in my neck of the woods and didn't wan't to order another part but I am usingby djinn5150 - Smart_Rap
Well would ya look at that I think I figured it out, this was a 2+ hour print and came out wonderfully. It really helps if your air conditioning isn't blowing across the print bed. I have a whole other slew of problems with this print but I think its in the modeling more then the printers fault. Was expecting a 2mm sidewall at the top, got 2.01mm; 3.87mm at the bottom, 3.9. z fell short atby djinn5150 - Smart_Rap

Awesome I'll try both, probably the aquanet first since I believe there is a can in the wife's bag of tricks Quote3.14159265359 * (5 + 0.43)=17.058848109 then for 1/16th steps and 1.8* per step - 200*16/17.058848109=187.585936609 esteps or rounded to 187.59 esteps per mm My brain finally kicked in and I came up with the same thing, rounded up at 187.586 but will probably go up to .59, didby djinn5150 - Smart_Rap
Usually I could follow that...maybe I have just been at this too long.... But what I have been doing is just this print a 10mm cube, measure then apply this formula 10/actual size * old step = New stepp for instance my last print 10/9.7 * 182.59011 = 184.434455 My shafts are 5mm, my fishing line is .43 I am going to walk away for a minute so maybe my brain can process what you are tellingby djinn5150 - Smart_Rap
New fishing line is installed and running calibration tests now. First 10mm cube came out ok, and definitely short on all axis. Will do one more them move up to a 25mm cube. I will most likely play with flow rate soon but want to minimize variables inbetween prints to find out what works etc etc, hopefully I wont be beating my head against the wall for too long. Would someone be so kind as toby djinn5150 - Smart_Rap
Yes it is a 45lb mono-filament, its what I had available at build. I will locate some spectra and replace that for sure. I am guessing that will have an effect on my steps so once thats done I will re-calibrate, Z steps are actually a little off after double checking the LM8 bushings, from what I can tell they should be 23.8mm tall and I just printed one at 23.14.

Not sure how to post images from my google drive folder but the link is here Located in the "prints" folder There is also a photo of the build in its current, albeit messy state. My flow rate is set to default at 1, Have not had any "knocking" that I am aware of, a bit of whining here and there but not bad, I don't believe the filament is slipping but I am only a man I can be wrong(if you listenby djinn5150 - Smart_Rap
Hello all, So first let me say I am new to the whole 3D printer world. I have built my first printer choosing the Smartrap. I have gotten everything working but with no consistency. I was able to get several calibration prints printed to within a .1 The problem comes when I try to print any replacement parts, specifically I really need a replacement x lm8 support, they tend to turn to swiby djinn5150 - Smart_Rap
