Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
I'm impressed with the Vex Pro 2 speed shifter and was already to buy when I noticed the output shaft uses hex rod.
The reason for wanting a round 1/2" shaft with a 1/8" key way is because this shaft will match up with a very wide range of sprockets and pulleys. In particular I would like to try out the belts in the kit of parts and substitute your nice 2 speed for the default single speed transmission. Only question is how can I make this work when my team doesn't own or have access to a lathe or a broach/press? Paul, is Vex willing to build a few special order shafts for smaller teams without machining resources? |

The Versa Wheels are shown as In Stock? Are they available now? Earlier there were manufacturing problems and they weren't available.

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
I received some VEXPro material today, from an order placed before kickoff. I'll be testing a fixed ratio gearbox and a Versaplanetary later on. Today we started working with the 7075 shaft stock and related components.
This stuff is really great! The first thing we worked with was some 1/2" hex shaft stock. Facing the ends we were impressed with how nicely it machines. It is noticeably harder than 6061, and this is apparent when cutting with a band saw, but facing the ends was not very different from facing 6061. The faced surfaces are beautiful. As promised, the hex shafts slide nicely into bearings with no sticking or jamming. The collars are nice and small, fit properly, and feel very secure when tightened. The hex shaft stock also fit into a hex hole that we broached in one of our standard steel poly-vee J-section pulleys using a duMONT 77713 that I purchased from McMaster-Carr (2875A24). The fit is a little tight, but we like it that way. I will be using VEXPro shafts, bearings, and hardware for a project in the research lab at my day job -- and I suspect a lot of this same stuff will prove useful on my team's FRC robot as well. Nicely done, VEXPro! :) -------- Edit: after posting I ordered a couple of gears for my day job project, and received notification that they have been shipped within 20 minutes of the order. Freaky fast, kinda like McMaster, or Jimmy Johns. ;) |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
222 is extremely disappointed that we received our two 3 stage ball shifters with a paper in each box informing us that the third stage gears were not shipped with the transmission and that they will be delayed.
Since the 3 stage transmissions and gears show as in stock as of this post we would like to inform others who may have ordered this 3 stage ball shifter of the gear delay. The team member who purchased the parts talked to IFI this morning and said that the gears should be in stock early next week. This means that we will (hopefully) have functional transmissions a week later than expected. While this may not affect our schedule too much it would have certainly been nice to know at the time of ordering rather than the time of delivery that certain required parts are not yet available. |

Additionally, it is worth checking to make sure your purchases will ship in a timely manner. I ordered QTY:10 of the 22T Hex Sprocket on Monday night, which was listed as "In Stock". When I didn't receive a shipping confirmation all day Tuesday, I called Wednesday morning to find out they wouldn't be in stock until Thursday or Friday. VEXpro then offered to ship them Wednesday if I was ok with not having the "VEXpro" logo and Tooth Count stamped on the sprockets. I quickly agreed to have them sent "as is". I'm no warehouse management expert, but if "In Stock" is advertised on the website, it probably should be on your shelves. I completely understand having to process a ton of shipments, but not having the products available while listing as "In Stock" doesn't seem right. Then again, I could be totally interpreting the situation wrong, but all I know is we won't get our sprockets until Monday :( [EDIT: While the initial estimated delivery date was Monday, it appears that our sprockets will be coming in today! Thanks!] Also, I'm still waiting to hear back on our replacement Hex Bearings from IFI, one of ours didn't fit the 1/2" Hex output shaft. I had 16 similarly bad Hex Bearings from AM, and after I called yesterday they had 16 new bearings in the mail within an hour! On a lighter note, we love our VEXpro Ball Shifters! And they come in such cool boxes! :D -Mike |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Michael and Brad,
I apologize for your situation regarding the ball shifter gears and the sprockets. We 100% quality inspect all of our custom made components (we lot check commodity items like bearings) and we found the engraving issue with all of the 16T and 22T #25 sprockets. We shipped out some without engraving but sent the rest to be engraved and will have them Monday. They are currently marked as "ships early next week" so you can still order them. This was a timing issue and I apologize for any inconvenience this has caused. We did have to ship a certain quantity of the 3 Stage Ball Shifters incomplete without the 2 third stage gears. Our rationale in shipping these incomplete was that we'd rather get the bulk of the shifter components out to customers and let them start assembling the gearboxes. We have shipped out all of the missing gears for orders that shipped without them and the 3 Stage Ball Shifters are now shipping complete. Both Mike's and Brad's (well, someone else on your team) gears will arrive at the shipping address today. I have sent both of you the tracking numbers via PM. For the stock situation, there are rare cases where our actual inventory and Web site stock status are not in sync, specifically when orders for larger quantities come in quickly. We agree that our customers need to know the actual status of items so they can have knowledge of when they will arrive. We move them to either "out of stock" or "ships in xx days" as soon as we are made aware of the stock status. For the VEXpro components, I made the decision to not put an item "out of stock" on the web site if it was going to be made available in a week or less, but rather put "available in xx days" so you can still order it. If it is placed "out of stock", then you can't even order the component. You'll notice that some sprockets and 2 of the VersaHubs are marked as 'Shipping Early Next Week' -allowing customers to place orders but informing them of the shipping delay. With regards to the hex bearing, our customer support received an e-mail just before 4pm yesterday regarding the bearing issue. If your issue is critical, please call our customer support so we can address it immediately. We will send your bearing out today along with an RMA number and a shipping label to ship the bad bearing back to us. Once again, we apologize for the issues you both had and appreciate the feedback. Please do not hesitate to contact our customer support directly. At VEX Robotics, customer support is our highest priority so if you are not satisfied with something please let us know. Paul |

I'd like to throw out that other than a interference fit between the gearbox shafts & gearbox bearings (0.002-ish), our parts have been really great. The 1/2" hex shaft and the piloting hex hubs are ridiculously nice for prototyping.
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
I just wanted to post an update that the gears were delivered today.
Had customer support told us that earlier today I would not have posted earlier. Consider our 3 stage ball shifter order complete and in time for our weekend assembly session! :D Off the Shelf FTW! ;) |

Besides, telling ChiefDelphi about the problem means that dozens of people who have a need to know, now know. If you hadn't spoken up, they would still be ignorant. |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
An FYI on some products we've added since the launch last month, you've probably heard about 2 of them:
The 2013 Drive in a Day Chassis and Accessories, along with details on recommended configuration for this year: http://www.vexrobotics.com/vexpro/ch...-in-a-day.html The Mini CIM and BAG motors: http://www.vexrobotics.com/vexpro/motor-controllers Pneumatics - we have a SMC Solenoid, Manifolds and some accessories available: http://www.vexrobotics.com/vexpro/al...manifolds.html Best, Ricky |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Received the Versa Planetary gearboxes yesterday that were ordered on Kickoff day. They look nice. One thing that's no big deal but I figured I'd mention is that in the future perhaps a tumbling or chamfering process needs to be added to some parts. Some edges are rather sharp. One slight difficulty I had was removing the little slotted steel motor adapter bushing once installed, if I decide to use a different one (or none). Is there a good method for this?
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
The bushings are a tight fit in order to guarantee a good clamp and good concentricity when the ring compresses. The easiest way to get them out is to use the motor they are designed for and put a slight side load when pulling out. This worked for me when doing testing.
Noted about the sharp corners. In some cases the manufacturer did not follow our print regarding breaking edges. We will improve this on future items. Thanks, Paul |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
We assembled the VEXpro 3 stage Ball shifters today.
This post is to alert IFI and other teams of an issue with the assembly of the 3 stage transmission only. Both of our transmissions had this issue and it took some investigation to find the exact issue. There is a gap between the stamped metal plate that houses the third stage bearing and the 1/2" hex standoff's. If you install the plate it will bend and cause other problems. It appears that hex molded into the transmission housing is approximately .05" too deep as the 3D model measures .25" and the actual measurement of the molded housing is .30". One fix would be to add shims between the 1/2" hex and the metal plate. ![]() ![]() |
