I have started over and I can't even get Johann's deltabot Marlin to comile without changing a thing. It gives me this error "qr_solve.cpp:7:18: error: time.h: No such file or directory " From what I can tell, I don't have a time.h library. I didn't have the issue before, though. I'm going to take a break and come back to it later. EDIT: I'm back. Richard, are you using your max endstops forby umdpru - Delta Machines
Thanks! I'm going to go back to the beginning. I must have screwed my firmware up at some point. I'm going to go back to Marlin-Deltabot from Git and restart. I really do appreciate your help, Richard! the first thing I notice from your pins.h is that you have your end-stops connected to the min pins and you disabled the max pins? On my 3dr, they're connected to the max pins and the min pinsby umdpru - Delta Machines
can you tell me what you have changed in your pins.h file?by umdpru - Delta Machines
I just found something interesting. I have commented out the min end stop pins in pins.h to disable them (used -1) and I just confirmed that fact. M119 with teh nozzle 50mm down shows all max pins untriggered, however, the Z-min pin reports as triggered. That's strange, right? EDIT: I just tried compiling with "DISABLE_MIN_END_STOPS" uncommented to disable minimum end-stops and I got a compiby umdpru - Delta Machines
I have a 3DR simple by JohnSL not a mini Kossel. The firmware was originally for a mini-kossel because the firmware used by JohnSL RichRap on his 3DR didn't support M666 as he used hall effects for the end stops which contained adjustments. Mine doesn't have any manual endstop adjustments so M66^ is the only way. The original smooth rod offsets are taken right from JohnSL's 3D CAD model. Hereby umdpru - Delta Machines
Well, this has become frustrating. For some reason, the M666 commands aren't having any effect on the Z tower offsets. At. All. I go from Z10 to Z-10 and there is absolutely no change in the offset on the tower. Is there some setting in config.h that I am overlooking?by umdpru - Delta Machines
My printer is short. It was a mish-mash of John's design and Rich Raps. The extrusions are 500mm and the effector arms are 200mm. I think I could probably shorten those up and get better height. That MANUAL_Z_HOME_POS was determined from measurements and M114 to verify. Here's a copy of my Config.h. I went through a lot of pains to get Marlin to work. Keep in mind, that I'm using Ramps 1.4 not prby umdpru - Delta Machines
Ok. Here's an update. I'm magically not having the issues with the Z tower. In fact, the arbitrary Z-5 worked out to get it right where it needed to be. Now I'm going to move on to adjusting smooth rod offset because the nozzle is "below" the build plate by about .4mm at the center.by umdpru - Delta Machines
That is basically what I have done with the exception that I first set the MANUAL_Z_HOME_POS to the thickness of a piece of paper (call it the paper gauge here forward). that left me with MANUAL_Z_HOME_POS = 124.2. Then I moved to X and then to Y and got the paper gauge set. Then at Z, the M666 command to offset the end stop has ZERO effect on the height of the nozzle. I mean, I set it to Z-5by umdpru - Delta Machines
Thanks. I printed mine at 50% infill in ABS. I may take the pieces apart and glue them together. ABS isn't anywhere near as rigid as PLA is so that oculd be some of what I'm seeing. The assembled pieces are flexing somewhat and I do have my filament reel mounted on top further exacerbating the problem. I have found this calibration "tutorial" that I'm trying to get through now. The major stby umdpru - Delta Machines
Is your's printed in PLA or ABS? I wonder if I didn't use enough infill. I'll make a video once I have it printing something again. In any event, I'm going to move on to calibrating the printer. I'm following this guide here: How are we 3DR users supposed to calibrate the end-stops without adjustment screws? I'm going to have to learn about M666, I guess.by umdpru - Delta Machines
Thanks RTurnock. I have a J-Head Mk IV from Makerfarm on my machine. I'm using a geared Wade's extruder. Does anyone have a problem with the upper end of the machine oscillating with print head direction changes? Mine can oscillate quite heavily during print head changes. I'm thinking of manufacturing a base and adding triangular supports for the arms to stop them from oscillating. It's introduby umdpru - Delta Machines
Thanks, Pierre. I seem to recall that bowden fed extruders needed a longer retraction distance?by umdpru - Delta Machines
Hi all, I finally got time to work on my 3DR simple after two months. It's working now. Not perfectly, but making shapes. What are the recommended retraction settings for this machine?by umdpru - Delta Machines
You need the paper towel in order to hold enough everyone and increase the surface area available for evaporation while"cold". This is the only method I use as it works great!by umdpru - General
No, I built it from scratch and used ramps 1.4. I didn't own a simple and didn't bother buying one. I got my 3dr simple kind of working (not calibrated yet) by following what the mini Kessel guys are doing.by umdpru - Delta Machines

Well, I ditched Rich's version of Marlin and tried the Kossel version Marlin here : I have attached the configuration.h for the delta Marlin. Rich's version of Marlin was quite old and doesn't support some of the newer features that are really required, especially by the #dr Simple, like M666 to adjust the endstops in software. I might remix the 3DR simple carriages to include a set screw for adby umdpru - Delta Machines
M119 reports the following: 13:57:39.745 : N50 M119 *63 13:57:39.747 : Reporting endstop status 13:57:39.747 : x_max: TRIGGERED 13:57:39.748 : y_max: TRIGGERED 13:57:39.749 : z_max: TRIGGERED I disabled the x,y,z min end stops using "-1" and reuploaded Marlin. It still does the same thing. It homes just fine but will not move in any axis using manual controls.by umdpru - Delta Machines
Hi all, I have some good news and bad news. the good news is my 3DR is alive - somewhat. The bad news is I can't get it to move via repetier host or pronterface. I don't really know repetier host yet which is why I tried pronterface. the machine was homing and crashing right past the end-stops until I dropped the homing feedrates down from 200 to 50. Now it homes each axis properly but itby umdpru - Delta Machines
I recently completed upgrades on a loaned Cupcake CNC . the only part of it left is the frame, motors and the heated bed I made an TwoTimes x/y lowrider for the x/y stage and eliminated the MBI electronics for a Ramps 1.4 setup. I also made and installed a MiZrider (less work than a twotimes Z-Rider). I also use a J-Head MK IVB and a Wade's Accessible extruder. Lastly, I installed a 30A 12VDC LEDby umdpru - General
The fact that the problem occured at exactly the same point in time and location in the print should point the finger at the G-code, in my opinion. that is, unless you have printed other objects with different G-code with success or failure at some other point.by umdpru - General

welcome back, John. Thanks for pointing out that picture on Rich's site. that explains how the LCD adapter mounts to the printer. the adapter doesn't line up with any holes in his LCD cover backplate, however.

Rturnock, I've seen that and looked at many different pictures. It doesn't tell me HOW the LCD is mounted. Rich has an LCD adapter in his github files but I can't figure out how it's used to mount the LCD. I even imported his parts into Solidworks and still can't quite figure it out. I'm just going to design my own mount. On another note, I have designed a J-Head fan duct for use with my versby umdpru - Delta Machines

Time to get reading, bucko. You can't possibly get a straight answer to that question as there are just too many possibilities. Many printers (if not most) will get to 100 micron resolution if they're tuned well. Note that it takes more than just the extruder to get that good, your while machine has to be dialed in. I would suggest you do a lot of reading. Take the initiative and learn. We can'tby umdpru - General
QuoteD-Wes I usually preheat the bed and hot end manually from pronterface using the set controls in the lower left. If I don't the hot end will not heat up when the print begins. The appropriate commands are there in the gcode, but they don't seem to work unless the hot end is turned on manually. It took me a while to figure out that the default values are editable.
