The issue is that as the z-axis travel increases the bearings that attach the sled to the router need to be stronger. I kept it reasonably compact to keep it rigid. Maslow is really designed to cut sheet goods that usually less than 3/4 of an inch thick. 1.9 inches of z-axis travel gives enough travel to cut like a 2"x6" (really 1.5" by 2.5")…although it isn’t really meant for that it is possible. > [@dlang](#): > > what is the max belt length that the mechanism will support? I have 13’ foot belts on there, but I think I’m going to try to ship with 14’ belts. The extra belt looks a little awkward when the belt is all the way retracted, but if I ship with longer belts everyone has the option to cut them down a little bit. > [@dlang](#): > > it’s not just the current accuracy, but also to see what the error pattern is > (is it curves around the middle like the original, or something else given that > the additional belts make it overcontrained) I will gather data on this and put it together in a useful way.

> [@dlang](#): > > so no encoder on the motor, just apply current in either direction? Yup. The motor does not contain it’s own encoder this time. The motor driver does have a current reading so we can measure the load on the motor, but position control is done entirely with the roller tracking the belt after the motor. Measuring the position at the motor wouldn’t be accurate enough because as the belt spools up on the spool the size changes and it’s not 100% predictable. ---

OK time to place your bets. how many backers will Maslow 4 get? Maslow 1 got 1,279 backers according to kickstarter. I’m gonna guess 1400 backers for maslow 4. ---

This time I don’t think so, but we’ll see if it gets uncomfortable. I’m very confident in our suppliers this time around so I am not stressed about sourcing the parts. I think that the limit would be we don’t want the community to grow so suddenly that it messes with the feel. I’m not ready to commit one way or the other on that yet. I don’t have a number in mind, but I’m open to pausing it if we feel like it’s getting out of hand. ---

Good old regular USPS, or anything that hands over to Canada Post on this side of the border. They only charge us the tax/duty for the parcel. UPS adds a $90+ fee, plus tax on the fee to pay the tax. It’s bonkers. ---

Yes, USPS is the cheapest. Sometimes Canada Post charges $5 for brokerage and other times they charge nothing. They will also sometimes charge federal sales tax. But UPS will charge the sales tax and shipping and they will charge $90+ for brokerage and handling. FedEX and DHL charge fees too though usually not as steep. ---

Honestly I sort of stopped thinking about the money as soon as we hit the goal. My todo list is organized based on how critical the things on it are to make the project a success and as soon as we had enough money to make it happen I shifted my focus to getting it done. It does feel good knowing that we are going to be able to build it though. The part I’m most looking forward to is when we ship them and people start building things. I’ll celebrate then 😀 ---

> [@bar](#): > > It does feel good knowing that we are going to be able to build it though. This is what i was thinking about. its an also an affirmation of your idea and proof that a lot of people want to support a new iteration of an old concept. I would have asked about the total backers but I am suspecting that some backers requested more than one kit or some may have just pledged a lower amount. In any case, its really nice knowing that there will be a large pool of users available who will be testing new ideas and changes and helping to improve the system as a whole.
