My question to you guys is! What Delta type printer would you recommend for me to build and use for my first delta style machine? I like the upright Delta designs and I really enjoy the mechanics of there build and how they operate. I am serious when I say I would really like an honest answer as to what Delta kit you would recommend!

Could you and Michael please post your printer settings if that's not too much of a trouble for you?

From the diagram in this post:

From this post with the delta offsets .pdf, it looks like the Smooth rod offset should = effector offset + delta radius+carriage offset unless I am misreading the diagram.
The default settings for the rostock 301 are:
Smooth Rod Offset = 160
Effector offset = 33
delta radius = 89
carriage offset = 33
Something is not right, the effector offset + delta radius+carriage offset =155 which is 5mm less than the smoothrod offset of 160mm!
Has anyone noticed this and found a way to correct it to get the bed leveling to work better?
Hello, I've found a way to level which I do very well.
The issue is to distribute the same distance (more or less) between script 1 2 3 4 so that when lowering the columns lower everything. This is achieved with the option DELTA RADIUS
I put you like I do:
1. Adjust the height of the printer so that the nozzle is as close to the bed as possible. I adjust the correct size (piece of paper) with the Zoffset.
2. I move to each column to adjust its correct height (piece of paper) with the screw. Home every time I correct a column
3. Once I have all three columns adjusted, script 1 usually stays away from the bed. Then I set Delta Delta so that:
By increasing Delta radius the nozzle moves away from the bed in scripts 2,3 and 4, ie in all three columns (do not lower the nozzle).
This is where we have to look and adjust delta radius so that script 1 is more or less at the same height as 2,3 and 4.
4. We adjusted script 2,3 and 4 and return to 1
If all goes well the nozzle will be correct in all points, if not, we return to 2.
If you have doubts or do not understand well please tell me, I will be happy to help.

Hi.
Here is a short review of my building and using of rostock 301
I'm new to this forum, but wanted to talk about this printer I just bought and have build.
This is my third printer, first was a Fabikator mini (hobbyking), second was a geeetech G2S Pro.
I dont need but i love to build machines, and to be able to print every useless plastic thing i want.
After my succesfull G2S Pro build, i wanted to try the diamond head, with mixing colors.
I bough This :
[www.geeetech.com]
I recieved it and easily finished the build in about 12 H (i'm quite slow, but it's a part of the pleasure)
The mechanics is quite similar to my previous build, the G2S Pro, and the wiring part is significantly better than on G2S Pro.
Geeetech building instructions were ok for me.
[www.geeetech.com]
user manual is... not fantastic. [www.geeetech.com]
Prefer Cura, and lower print speeds...
The firmware of this printer is not open source. On geetech forum, my name is also Raoulito9 (don't ask why a so lame name), and I already posted sometimes, alwais asking to release source code, no effect for now.
Here are the main steps for me to pay attention when building that printer, and getting it to print something.
1 When assembling, verify the rods lengh; mine where correct, exactly 200 mm.
2 When configuring printer, after levelling the bed (caliper needed), on printer screen adjust printer rod lengh (200 for me), printer heigh (225 for me) and Z offset (0,2 for me), Rod radius was 93,1 for me.
2,5 Add some elastic bitween rods, to limit head loose moves.
2.6 pay great attention when mounting the screen holders that are very weak, I broke both of them...
3 Unmount the useless extruder fans. Yesss, you get 3X 40 mm fans for free
4 change crappy stock etruder mechanism with something serious ( metallic and where you can ajust spring). THAT WAS IMPOSSIBLE TO PRINT BEFORE THIS STEP
5 Keep bowden tubes as short as possible (50 cm)
6 Push vrefs : 0,85 for steppers, 1,04 (max possible for me) for extruders (stock vref loosed many steps for me)
7 When configuring in repetier, use Cura instead of Slic3r.
8 I print PLA; right temp is 210 for me, no heating bed is needed.
9 Top and bottom thickness = 1mm
10 Speeds : All prints bitween 15 and 20 mm/s. Moving 40 mm/s.
11 retract : 5 mm
12 end code script, erase the disable steppers command, replace by G28 (home) command.
The printer is way slower than whet is said by geeetech
Above 30 mm/s, extruders can't follow and loose step, and quality is awfull (for me)
Mixing feature is not supported in gcodes. Only knob and printer screen.
Links :
Firmware
[www.geeetech.com]
Burning specific 301 Firmware :
[www.geeetech.com]
My experince.
Something is unclear for me in new firmware :
Here is what i've done :
1 put the jumper
2 flash bootloader (Ok, I see the progress bar going on, and the prog tells me it's succesfull)
3 remove jumper
4 launch hyper terminal, right com port, 115000Bauds
5 wait the writings as on your screenshots.
6 hold C Key + disconnect icon.
7 Push 1 key
8 send file Ymodem (new 1.0.0.2 firmware) OK, i see the progress bar, and when finished, some chinese writings in hyper terminal.
Disconnect.
I'm happy and burnt new firmware....
I Reset printer
I verify the versionof my firmware into the control menu from my printer, and it is still 1.0.0.1...
Something went wrong for me but... ?
I tried again, and that time, the new firmware has been burnt. When i verify in printer menu, the control then version, i'm with 1.0.0.2.
No need to burn bootloader again. one time seems enough...
The right 1.0.0.2 firmware is attached to that post.
Because the mechanic is similar with the G2S PRo, many mods are compatible with 301
Useful mods for that printer :
This one is a must. [www.thingiverse.com]
This one is simple, but i made it myself. many alternatives exist. [www.thingiverse.com]
This one is my favourite led holder : [www.thingiverse.com]
Extruder metal kit; without it, impossible to print anything. Stock ones are cheesy craps.

Hola Rene, hola a todo el mundo.
yo , sinceramente soy muy nuevo en las impresoras 3d, y he conseguido que funcione casi a la primera. No sabia los ajustes de Vref ni nada, y era eso lo que me fallaba.
Supongo que habras repasado todo el montaje, los Vref de acuerdo con tus motores de ejes , tension de las correas,etc
Te mando una foto del elefante, lamentablemente me quede sin filamento
esta pagina no deja mandar archivos mayores a 600 KB , pero puede verse como tiene algunos fallos, aunque la calidad sea buena en general
No entiendo tu pregunta Rene, yo tambien uso el traductor
