Lead Screw Upgrade Kit

Hello All!
Unfortunately we had an overwhelming amount of pre-order's for the Lead Screw Upgrade kit. We have now opened up the product page for "Pre-Orders". All kits will ship starting August 25th when our shipment of kits is expected to arrive. The price of the kit is $100 and that includes two stepper motors with lead screws built in, and the new Z axis end stop brackets. Here is a picture of what is included:


Here is a URL to the PRE-ORDER page: http://www.robo3d.com/products/lead-screw-upgrade-kit
Please remember, these WILL NOT START SHIPPING till August 25TH. Let me know if you have any questions or concerns.
Regards,
Harry

 

For the beta printer it is a firmware upgrade (screw thread size is different).
Might not need firmware changes for the R1. The real difference with the R1 is the lack of the couplers (which will help reduce ribbing). Unless they are changing the threads on the rods the firmware is probably OK for the current R1.

 

I have printed objects 10 inches tall without issues (albeit slowly at the top). I use a beta, no top supports.
I am not saying they are NOT helpful, but they don't seem too bad without them.

 

Just an FYI, it is different than the R1, the number of Z Steps is only 800 in the firmware as opposed to 2560 for the 8 mm threaded rods. As far as I could tell from a cursory examination that is the only change from the R1 firmware, which is still Marlin 1.0.0. I am not going to investigate this any further since I almost have 1.0.3 completely debugged for the Robo R1

 

800 sounds... not right, but hopefully it is.
Since it is all new (stepper too) anything is likely/possible.

 

Configuration.h, as usual. Line 445. Also if you install this do an extruder calibration. They still have the 723.38 number for E-Steps, I think the real number is between 780-810 or so.

 

I lied, here is every line that is different between the leadscrew firmware and the latest R1 firmware:

Code:

LS - #define CUSTOM_MENDEL_NAME "ROBOR1PLUSV1"    //robo
R1 - #define CUSTOM_MENDEL_NAME "ROBO3DR1V3"    //robo

LS - #define RIGHT_PROBE_BED_POSITION 205
     #define BACK_PROBE_BED_POSITION 230
R1 - #define RIGHT_PROBE_BED_POSITION 200
     #define BACK_PROBE_BED_POSITION 240

LS - #define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,800,723.38}  // default steps per unit for RoBo 3D R1
R1 - #define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,2560,723.38}  // default steps per unit for RoBo 3D R1

LS - define EEPROM_SETTINGS
R1 - //#define EEPROM_SETTINGS

That is it! At least EEPROM writing is now enabled by default, still didn't change temp PIDS or ESteps. Only line not cosmetic is the DEFAULT_AXIS_STEPS_PER_UNIT.

 

WooHoo!

 

Hey Frank, you didn't have those Z switch brackets in your kit?
They should be in a little bag. If not message me and i"ll get you a pair mailed Monday.

@mark tomlinson 800 is right actually.
And yes the guide is linked above thanks to @Taylor

diff configuration.h from the new one with what you modified and you are probably going to see all of the differences.

Diff the whole folder and you certainly will. I don't know if they modified this from a newer marlin branch or from the last one they used. (good question though)
