I'm on Linux and have the same issues. I'm sure it's a memory problem because if I load several large items to print it not only takes forever to change anything, a crash is sure to happen. I can't use Simplyf3D for the parts I'm printing. They have mesh problems that slic3r handles but Simplyfy3D repairs incorrectly, making a solid layer including any holes that should be there The parts are fby voi9viper - Slic3r
I've been playing with support becuase my printed parts for a MPCNC needed high explosives to remove the support material. After a while I realized Contact Spacing is not space between the support and printed object, it's the width of the solid area of contact. For example, if you set this to 0.2 mm with 3mm spacing every 3mm there will be a line of material 0.2mm wide on the part, with bridged mby voi9viper - Slic3r
sort of related, what commands control a second fan? Is there a list of commands the dc42 firmware supports? I have looked but can't find a way to list the heights of the probed points for auto level. I just ran G32 with option 6. Cool handle Viperby voi9viper - Duet
I apologize for newbie questions, but I just got my printer running with the latest dc42 1.09r code, and www files. Should I be using your firmware branch instead? It's a delta printer with a duet 0.85 board. The web interface no longer tracks layer changes for some reason. This changed mid print. Before reporting any bugs I want to be sure I'm using the correct software.by voi9viper - Duet
You have the homing direction wrong in your config. You want to home to max. If one motor moves down instead of up, adjust the wiring. You dont want one motor inverted and two not in the firmware. It sounds like you may have some loose pins in the connectors. Make sure they are all firmly seated. They can get pushed out when you connect them and it's hard to notice.

its' very pretty, but LOTS of unnecessary weight. I'll bet you can get the down to 60 grams easily, probably more. The effector is much thicker than really necessary. How much water flow is necessary to keep the cool parts under the melting point? i would like a smaller version.by voi9viper - Delta Machines
This is probably going to cause an argument, but I'm going with no. With great materials and large enough rods yes it could be stable, but if it's not adding bracing is almost impossible (welded brackets would work). That said I think the basic kossel extrusion build is weak at the top corners especially. I'm trying to figure out how the make my large kossel more stable.

diagonal rod length affects X/Y size/scaling, but I think it's something else. The only thing that I know for sure that affects Z scale is steps-per-mm, and based on your results this seems most likely to me. This is easy to test without printing anything. Move the nozzle to x0, y0, z30. Measure the real height, move Z up at least 30 mm, the higher the better, but no higher then you can measure wby voi9viper - Delta Machines
nice concept dc42, so I bought one. Im hijacking, but do know anyone the make a metal effector for a kossel? One that works with e3d hot ends?by voi9viper - Delta Machines
I think a belt or pulley is slipping. tighten all the grub screws on the pulleys. One of those per pulley should ride on a flat on the shaft, also.by voi9viper - Delta Machines
I just hate imprecission too. syncromesh as in trasmissions? Or is it something new, which I suspect if patents apply. I'm dating myself, but my 71 firebird had a syncromesh tranny I think.by voi9viper - Delta Machines
is just one corner too low, or is that from the photo?by voi9viper - Delta Machines
I had not considered the additional resolution using a 16 tooth vs 20 tooth pulley, but it is there, you have to change steps per mm to compensate. My idlers are two flanged bearings riding on a cheap bolt, but they seem to work. A belt is never going to be your most consistent drive, but it looks like they are more than accurate enough to not be the limiting factor for a delta bot. The extruderby voi9viper - Delta Machines
Smoothie uses a text config file on the SD card. It's very easy to set up. I spent less than 2 hours and had the printer running correctly. I have not even looked at the source code. They even mount the SD card over USB so you can edit it while the card is in the board. There are also extra G666 commands so you can change the configuration on the fly. The time saved is worth more than than priceby voi9viper - Delta Machines

I cheated. I had a Azteeg X5 on order, and it came in today. The first thing I did was home the printer, and the speed scared me. After a couple of minor issues like the Z-probe not enabled in the smoothieboard firmware the first G32 command was perfect. Print speed is way way higher than the Mega2560/RAMPs 1.4 boards, and the connections were even easier. So was the initial setup. For a littleby voi9viper - Delta Machines
I had a TAZ 5 and never got PLA to print right. ABS was so easy I stuck with it. Now I'm trying it again with my new Kossel. I hope it works this time. I think the upper end cooling is not perfect, and when the extrusion rate slows plastic melts in the cold end , and jams. I have no idea how to fix that.by voi9viper - Delta Machines
Lol, I just installed a Azteeg X5 mini and had the same feelings. There is something crazy either in the board design or smoothieware. My power supply is a development unit I got from my job, with knobs to adjust volts and amps, and amps were turned way down. WHen I set the hot end temp the speaker/buzzer started making a scary hissing noise that sounded like something shorted !! With the supplyby voi9viper - Delta Machines
I modified my z probe to prevent wobbles, so i am about to give this another try. Where did you get the firmware you are running? I want to grab a copy, use my Configuration.h, and see what happens.by voi9viper - Delta Machines
I confirmed that y-80 is at the front, and y80 is at the back in front of the Z tower. Your directions are reversed. -X is to your left, +X to the right. I looked at you Configuration.h file and it looks ok. It does have #define DELTA . Can you confirm that looking at the RAMPS board with the three steppers driver cards at the bottom the green wire from the motor connectors are on the left?by voi9viper - Delta Machines
use the following commands for testing G28 ; home G1 Z20 ; goto Z20, just to be safe, mark where one of the carriages is G1 Z50 ; measure to your mark, did it really move 30mm? G1 X-80 ; should go to the left edge G1 X80 ; right edge G1 X0 Y80 ; back G1 Y-80 ; front Y may be negative in back. I don't remember.

I just built a chinese Kossel XL from HKBay. I wish I had seen the Folger Tech kit. In my opinion for the price it's a great kit. It has many little upgraded parts like twist lock t-nuts, aluminum corners, etc. I think you will do fine with just the kit to start with and the parts supplied are actually upgrades for most kits, like the 30 amp power supply, aluminum corners, covers for the extrusby voi9viper - Delta Machines
is it jamming in the extruder, or the hot end? Do you have a fan cooling the heatsink finned part of the hot end? The top part, called the cold end, needs to be cooled so the plastic only melts in the aluminum block at the bottom. If heat is climbing up into the finned part you can get jams like you describe. You said you have several fans, but not what they cool. What material are you printing?by voi9viper - Delta Machines
I have not tried my Kossel 250mm heater yet, but on my TAZ 5 (300x300mm square glass) the heater was glued to the glass with 3M 90, and that sat on top of an aluminum plate. I think you have the heater glued to the aluminum plates bottom side. Flip that plate over and see how it goes You will lose temperature where the glass is not over the heater, of course.

You can put a large cardboard box upside down over your printer. Way cheap enclosure, and it helps. The best thing for you I think is a PEI bed. You can get 1/8 inch sheets from Grainger, but they are $80. You can go cheaper with a 1/32 inch sheet and laminate it to borosilicate glass, and the glass is around $15, plus $23 for the 1/32 PEI.

Where did you get their firmware? I got no instructions and can't find their version of Marlin. I'm a developer and pretty familiar with Marlin on a cartesian TAZ 5, but the delta code is new to me. My first testing had about a 5mm rise in the center so delta_radius needs to be larger. I'll try your method and post the results in a couple of hours. Thanks again.by voi9viper - Delta Machines
I calculate my max Z height as 447 mm, this seems twice as high as everything I've found online. The Z endstops are at the top, of course. Am I doing something wrong? Other measurements seem a little large, arm lenght is 335mm, delta_radius 190mm. Thanks, I'm going to check out dc42s firmware tonight.by voi9viper - Delta Machines
