FOUND IT!!!! IT'S OK NOW

I did a comparison between my two memory cards. On the Card that was not working, The directory structure with the folders that is supposed to be in the WWW folder was in the root.

I moved the files into the www folder, power cycled the machine and all it well. I am connected.

Sorry to waste so much of your time. I even confirmed the directory structure in the wiki and it is clear that the folders are showing in a www directory.

Really, I'm actually not this stupid normally.

Thanks for your patience!! I will never make that mistake again

Extruder Adjusted

Printing Calibration Cube.

Print is looking very good. X and Y are 20mm.

I can't thank you all enough for the help and support that you have provided. You are all consistently knowledgeable and helpful every time I contact you.

My printer is completely silent except for the fans that are cooling the main board. There is no motor sound at all.

I am really very impressed with the Smart Effector.

Is there any way I can adapt my cartesian printer to support one of these? My current hot end is a square unit that mounts via screws through the top. It would be great to be able to bolt one of these on somehow.

(edited for spelling)

For my purposes, I consider this thread complete with very high satifaction!

Thanks
Tim

Hi
I am trying to complete my Cartesian Printer, and I believe I am up against my lack of electronics knowledge.

I am having problems with my Y axis. There is another post that I have been reading which seems to be having the same issue where the motor is skipping (for lack of a better term.) My print starts out correctly and then the layers start positioning themselves incrementally forward.

The advice in the other thread is discussing back EMF and the use of the wiki tool.

I have put the results in because I don't know what to do with the information.
I am not sure about the resistance and inductance as they were not on the site where I bought the motor.

Here is the detail from the drives section of my config.g

M350 X16 Y16 Z16 E16 I0 ; Configure microstepping without interpolation
M92 X400 Y800 Z360 E84.75 ; Set steps per mm
M566 X40000 Y40000 Z18000 E7200 ; Set maximum instantaneous speed changes (mm/min)
M203 X60000 Y60000 Z16800 E72000 ; Set maximum speeds (mm/min)
M201 X250 Y250 Z250 E250 ; Set accelerations (mm/s^2)
M906 X950 Y855 Z855 E855 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Any observation / advice would be greatly appreciated.

Thanks,
Tim

Hi wc97. I believe yours is indeed the post I was reading.

My Y Axis is completely non standard. it is a 20x60 V-Slot. On the wide side which is horizontal, there are two slide rails.

Each of those slide rails is mounted in the outer two tracks of the three that are there. There is a OpenBuilds plate 80 x 150 mounted to the two sliding bearings lengthwise along the Y Axis.

In the center of the plate is a lead screw block. It's not the right thread for the lead screw, so the block was drilled out. At the end of the plate is a bronze lead screw holder from an old Z axis gantry that is the correct thread.

So, the lead screw rotates in the bronze adapter which is attached to the build plate which moves the build plate. It is actually very stable and precise. The block is really there just to support the lead screw.

With the two slide rails, there is almost no friction on the axis. There are some other open build blocks that are mounted to the plate and extend out from the plate in a Y configuration that lines up with the two back corners of the heat bed and the front center so that I have a three point level system.

I ran this for more than a year when this printer was originally a Tevo Tarantula and the motors where all Nema17 motors on 12 volts.

The configuration is now a 500mm x 500mm x 500mm cube. Centered on the outside of each side are 500mm openbuilds motion systems driven by Nema23 motors. Connecting these two drive systems is a square gantry that goes through the inside of the cube. This is the Z axis.

The Y Axis is mounted on the top of this square gantry.

The X axis is mounted across the top of the cube and handles the hot end.

The Neam23 on the Y Axis is a .9 degree motor and the overall plan was to get another one to replace the 1.8 Nema 23 that drives X currently.

The system is powered by 24 Volts. I may replace the hot bed with a larger one as the plan for this printer was for large objects.

Any other questions, please let me know. This printer has been a tank for me and I really only got into trouble when I upgraded the motor. I'm sure it will get sorted out and I will get the correct settings into it.
