Hi all,
Just wondering what is left to do on the shapeoko. Two weeks ago, I believe, Marvin said we needed to do the following: (please correct me if i am wrong)
Is there anything else? What should be the priority?
Thanks,
Tiffany
Tiffany,
I think you have it all covered in your list even with the correct priority.
I think these are the basic things we need to do in order to have the shapeoko fully operational.
Although we could add a bunch more things to the list . Starting with these first would go far way
Marvin
Was there also the implementation of an e-stop button? what about the addition of limit switches (like the gigabot has)?
and for the electronics enclosure, would 3d printing this be sufficient?:

Thanks,

Estop - must have
Limit switches - optional upgrade
Hi all,
I also updated Marvin’s list with these items:
1/ Improve the mounting of the arduino+Gfield. the plate that I designed is a prototype
2/ Add cable chain on the X and Y axis (maybe Z). Someone started to print the part for that but I don’'t know who.
3/ find a way to prevent the USB plug to be disconnected (U shape, cable clamp, Gromet?)
4/ Mount the DC spindle and testing the speed controller ( I have a complete schematic but I don’t know how to order components)
For me the first priority task is to have a proper way to clamp the material when milling. As far as I know, we still don’t have any waste board with clamping capabilities. I proposed two weeks ago, a plastic (ABS ou else) board with T-slot (as you could see it in the attached pdf3D).
I think it’s the best way but I don’t want to impose it to the other (I’m a newcomer). Either solution chosen, I could help for this step.
For the cable, management, we just need to 3D print the parts for the cable chain, I already design a stand for it that we could milled from a piece of wood.
For the other spindle, i have already test it last Tuesday with a power supply. The difference is huge! If we want to use it, we need to build a speed controller. I have already design one. We now need the components…
I could come, next Tuesday, with a bill of material and put it on the new business.

Can we mill a t-slot table on the RongFu? Do we have drill rod or t-slot mills? Do we have access to like >5/8 aluminum plate?
Julien -
Apologies for not replying to this sooner. I skimmed it last week, and meant to leave a comment that for some reason even in acrobat reader, I’m unable to display the attached pdf. it simply appears as a blank page for me.
I’ll take item #2 on your list, and finish printing the cable chain this week.
For #4, yes. Please do assemble a sample bill of materials for the motor controller you have in mind. We can review it and get a vote on the docket for next week. It seems that Hive members most commonly order parts from Mouser or Digikey. I’ve had good luck with http://www.circuitspecialists.com/ for various components as well, and they stock a wide selection of reasonably priced power supplies. Any of these would be a great place to start if you know precisely which components you’ll require
As far as the work holding system is concerned, I’d like to review the hive’s existing collection of router bits both to see if we have anything on hand, and to confirm our available collet sizes. If you’ve already done this, let me know. I’ll be happy to order an appropriate t-slot bit. As we discussed Tuesday, we can mock up a slotted spoil board in plywood or MDF to test everything before committing to more expensive material.
Thanks again for taking point on this project. It’s exciting to see it coming together.
Hello everyone,
Matthew,
Can we mill a t-slot table on the RongFu?
I have to check but I think so. We only could use it for metal or plastic machining.
Do we have drill rod or t-slot mills?
Not that I am aware. it will be an item of my proposed BOM.
I want to buy ( if necessary) a t-slot cutter that is dedicated for the 1/2" nuts (https://www.grizzly.com/products/T-Slot-Cutter-1-2-/H5912). Before using it, it is necessary to mill a slot with an other bit to allow the T-slot cutter to pass.
Do we have access to like >5/8 aluminum plate?
We (Ryan, me and Jim) have first decided to give a try with a plywood board. Then, we would maybe switch to an ABS board. In my opinion, it is useless to put an aluminum board on the Shapeoko. the frame of this small CNC isn’t strong enough to mill big metal part AND after the slot milling we still need to level the board with the spindle. For now, leveling a aluminum plate with the actual “dremel-like” spindle will result in a crappy surface…
As we say in French, using aluminum for that it like give marmalade to the pigs. it’s not worth it.
Ryan,
’ll take item #2 on your list, and finish printing the cable chain this week.
Thanks! i don’t know how to 3Dprint for now. I really need to take some classes at the hive before buying mine.

OK, it’s already on my bucket list. I have check on circuitspecialists. They have a power supply that could fit with our needs.
As far as the work holding system is concerned, I’d like to review the hive’s existing collection of router bits both to see if we have anything on hand, and to confirm our available collet sizes.
OK, the only available collet on both the “dremel-like” and the DC spindle are 1/8". The collet size ise ER11-A. There is some available for 1/8, 3/8, 1/4 shank diameter at Inventables for around $5 each.
I have check on my pdf3D files and it’s working fine. I have add a picture in attached files. Maybe you have to update your acrobat reader version.

I did a quick skim and couldn’t find this information.
What do you guys need in terms of power supply? I bet either the hive or I already have what you need.
-D
The spindle is a 48 V DC motor for an input power of 400 W (https://www.inventables.com/technologies/quiet-cut-spindle)
So power supply that could output 48 Volts and around 8.5 Amps.
I’ve got nothing with more than an amp at 48v and nothing with more than 24V at 10A. 
This will probably cost some money…
-D
48 volts is not a common voltage in electronics power supply… you can’t find this in computers and it’s probably the first source of high power supplies.
The price of this kind is between $100 and $150.
Telecom. 48V very common.
-D
Right but it is not easy to have access to the telecom bay. Comparing to all these PC power supplies you could find in dumpsters… I will also check on Craiglist.
