Thanks for all the help and comments. I now have my Hadron Ordbot X any Y axis up and running with the software seeing the Microswitches. I have to get another two Polou driver boards to bring up my Z and extruder steppers. For now I load a STL file just excersize the X and Y axis. I have not built anything in a while and was extremely pleased with my Gen 7 1.5 board. I was a little concerned sby hobergenix - Next Wave Electronics Working Group
I did some reading and am aware of the internal pull up resistors in the ATmega. I am not sure how to modify or add that to the config.h file as of yet. I am new to all of this and just learning the ropes so to speak. I used the config.h file that was for the Ver 1.4 board and renamed it to config.h file. I see the following line in the config.h file /** \def USE_INTERNAL_PULLUPS internal pulby hobergenix - Next Wave Electronics Working Group
I am bringing up my gen 7 V1.5 board and have loaded the Tcup firmware. I have motors moving and it is seeing my opto endstops. I am in the process of moving the electronics off my test bed and onto my Hadron Ordbot frame. I am going to be useing Microswitches for the endstops until I get proper mounting and sensor trips in place for the opto sensors. I have the microswitches wired with the comby hobergenix - Next Wave Electronics Working Group
Thanks for the pic. That gives me a better idea on mounting. I am not too keen on useing springs but I am going to order some to have on hand. I think I will stay with useing the large paper clip clamps to hold the glass down for now. I am waiting for the glass plate and will get varrious sizes of serews and expierment for now. Your pictures gave me a better view of where the heat bed sits. Miby hobergenix - Mechanics
My frame and just about all the mechanical is assembled. I ordered a thermistor kit for the heatbed. My next step is to order a Borosilicate glass plate. I am still looking at how others have mounted the heatbed to the aluminum plate. I have seen quite a few web pages on the assembly of the frame and mechanicall but none seem to go into detail on mounting the heat bed. Their was one youtube videoby hobergenix - Mechanics
I am in the process of building a Ordbot Hadron. I just received my MK2B heatbed and was wondering what is the best way to mount and level it onto the aluminum plate. I have read about useing springs, stand offs, or just long screws with nuts for leveling. Any suggestions or links to a page explaining this. I am not sure how high the heatbed should be from the aluminum plate or hardware required.by hobergenix - Mechanics
I ended up buying basically the same thing fot about same price. After I cut the two pieces in half I will end up with four rods. I also purschased a Z Axis stabelizer kit from the Maker Slide store. Your supposed to pop the threaded inserts out of the Z-Axix nut block. The Maker Slide arms sit underneath the nut blocks and allow the rod to move a little to make up for any wobble. Atleast thats tby hobergenix - Mechanics
The Ordbot Hadron build calls for two M8 x 245 threaded rods. I have seen it sold in 500mm legnths and I can cut it in half. It comes with out any nuts and is basic studding material. I have seen 5/16-18 threaded rod attached to a flex coupler sold on Ebay for about 18 dollars each. I am new to the 3D world and was not aware that I could use other pitch threads. I have just built up most of my frby hobergenix - Mechanics
I was thinking the same thing about bargain lead screw. wheather it would be straight enough. The legnth of the right and left Z-axis threaded rods are 245mm. I can buy a 500mm threaded rod stainless for about 8 dollars plus shipping and cut it in half. The second optition is to go with the combo kits of motor, rod,threaded nut and flex coupler for about 60 dollars each. I bought the Maker Slideby hobergenix - Mechanics
I am getting close to completing my Hadron OrdBot and in the process of buying the threaded rod for the z-Axis. I purschased the 8mm shaft couplers and a Maker Slide stabelizer kit. Any suggestions on the threaded rod. I have 8mm threaded rod on ebay made from mild steel. Is their a particular material I should look for. I have also seen a few of the lead screw kits that cost about 60 dollars eacby hobergenix - Mechanics
I was considering making a 3D printer useing the ORD Bot style frame. Would I run into any problems with this setup or any special consideriations. The Ord Bot frame looks very simple and scalable to larger version. Mikeby hobergenix - Next Wave Electronics Working Group
