I am newbie or should it be NewBee to the OpenBuilds family and the boxes for my Workbee 1010 arrived late yesterday afternoon. It is like Christmas in February! All appears to have arrived safely due to the great packing job. I am currently unpacking and getting the pieces organized so I can start my build. I have been looking forward to this project and hope to put it to good use. Roger
Welcome Roger! You have joined the most supportive community so don't hesitate to shout out if you get stuck - and we are all learning so do pass on the things you find out that might benefit the rest of us. Have fun. Alex
Thanks! To everyone. I do have a question. Someone had posted a link to a .pdf copy of a manual for the Workbee but the link no longer works. Is there a place I can download the manual to the new Workbee1010?
I dont recall ever seeing a pdf manual for the openbuilds workbee, but ooznest has one. Their machines are slightly different, but they did help me in my build for things like adjusting the wheels and nut block. They are here: WorkBee CNC Machine For the openbuilds workbees, follow the build videos here:
Thanks! Especially for the quick reply. The old link was to Ooznest but no longer worked. The schematic visuals are a help to me as supplement to the videos. One other question is on the screws which hold the stepper motors to the Y-plate -- Do you use Loctite blue on the threads? Thanks again for the reply! Roger
I used blue loctite on any screw that didnt have a nyloc nut on it; including lock collars and motor couplers.
Manuals are here...just scroll down to "Mechanical assembly" and grab the files Assembling Your WorkBee
I just finished up on Step 11 of the video - Mounting Z-Axis plate to X-Axis plate. It is starting to look like a machine as opposed to a pile of plastic bags full of parts.
I am down to Step 17 on my Workbe 1010 and have found a potential problem. The last instructions of the step is to install the Black Angle Corner Connectors to the Y-End Plates using 12mm M5 screws and the Black Hex Nuts. The problem is that a 12mm screw only engages the Black Hex Nut with several threads and does not even reach the locking nylon material. I have attached two photos one with the screw tightened into the nut and one with the screw held in place with the nut taped beside it to show the depth it engages the nut. Are the instructions wrong and a 15mm screw should be used??? On hold waiting an answer.
I figured as much. Problem is the remaining 15mm low profile screws are needed to complete the base frame. They are used for attaching the End plates to both y-axis C-Beams. I am coming down to the end a finding I am short some small parts. I need to figure out who to contact to get them in the mail.
The build is up to Step 20 in the video. Took a little time to get it squared up. Planning on adjusting eccentrics and installing lead screws tomorrow. Possibly getting some of the wiring done depending on how many "honey do's" I have to take care of.
Getting closer! I have a question that came up while installing my NEMA 23 High Torque steppers which I ordered 4 of. After unpacking them and during installing. I find that I have three (3) that are 2303HS280AW-OB and one (1) that is a 2315HS300AW-OB. Is this going to cause a problem when setting up the machine with the xPro V-4 since one is a 3 amp/phase?
Good to know on the current but wasn't sure if having various torque ratings would pose a problem. I removed the higher amp one since I had installed it with the other y-axis stepper and didn't notice the difference. I will probably install it on the x-axis since it has a little higher torque rating. Thanks! Roger
I have 2 different amp motors on my machine. Others do as well since Z doesnt need a lot of torque normally. I'd just make sure that if you have a slave motor that it matches the master motor.
Only one of those sounds like a high torque stepper. Is there not a noticeable difference in size between the two models?
The length of all four of the steppers is 3-1/4" (83mm) which is bigger that the standard Nema 23 on the parts store site. I really would like to know since I paid a premium to get the high torque steppers.
If they’re all 83mm long then it sounds like whoever etched the numbers on the end made a mistake. The real 2303HS280AWs are the 175 oz-in steppers and are only 57mm long. You might check with the shop to verify but you can probably assume all are 3 Amp 2315HS300AW steppers.
OpenBuilds High Torque is about 85mm tall. Significantly taller than standard NEMA 23. If you did not receive what you expected, we'll make it right! Just contact customer service at http://support.openbuilds.com/support/home
Mary, The steppers that I received; three (3) that are labeled 2303HS280AW-OB and one (1) 2315HS300AW-OB. All four steppers are 83 mm in length. The confusion is caused by the labeling on them. The other issue being able to set them up for the correct current rating. Is there any way to test or verify their ratings. Thanks! Roger
Same height = same motor. Discovered that some of the motors had the incorrect part number lasered onto them at the manufacturer. The correct part number for High Torque motors ends in 300. Apologies for any confusion!
I finally have the mechanical portion of the Workbee assembled and am working on the electronics this morning. I have connected the LED ring just to test the power supply, check and set the 24 volt load output. I figured it would be less expensive to replace the LED than a blown xPro V4. One issue I have run across is the stepper wiring instructions in the video. First I have the pre-wired steppers with a male connector on each. In the video the wiring order is where coil A1=Red,A2=Blue, B2=Green and B1=Yellow. With the new V4 controller which has female connectors as a wiring check you could just plug in the stepper directly into the board. As shown in the attached photo the wiring order is flipped with the A-coil being Yellow/green and B-coil red/blue. How critical is this to the setup. Thanks! Roger
