![]() I am really frustrated with my Stepcraft 840. In the preview window, my model is, indeed, exaggerated in the Y direction with a ridiculously long toolpath travel.Īt this point, I am out of further suggestions after exhausting my research efforts. I tried that processor and the arc errors went away, but now I am left with a toolpath job that extends beyond the 840's Y-axis softlimits, according to the UCCNC warning. Another Stepcraft member posted a UCCNC processor that was provided by Autodesk for use in controlling a 4th axis. I thank those members who have posted their results under this section of the forum.Īfter building my CAD model in Fusion 360 and selecting Mach3 as the post processor, I load the g-code into UCCNC only to be surprised by a list of arc error alerts and a toolpath preview that is pitifully inaccurate. They are the same problems that trouble me, but I have made some painful progress, as a result of this forum. I have read about problems that other users have experienced. Aside from that first test job, my 840 has been useless. That file had been previously generated by some software other than Fusion 360. To date, the only piece that I have been able to machine is the Stepcraft logo provided as a sample file to test the machine following its construction. Sadly, though, Fusion 360 and its list of post processors are not enough to adequately control my Stepcraft 840 model. I have used Fusion 360 for about one year to successfully generate the g-code to control my other CNC machine. In short, it is a fabulous piece of software for all professional engineers. As an electrical engineer, I rely on Fusion 360 for all projects assigned to me. It is important to follow the Youtube videos for supportīefore my purchase, I was expecting to use Fusion 360 as my CAD program of preference. The assembly manual is not free of errors, I will confess. It took me about one week of assembly time to completely build the kit. ![]() It is interfaced with the UC100 dongle device and controlled by the UCCNC software supplied with the purchase. My machine is an S840 that I purchased last month. I have read every post related to my problem, but no real solution is available. I don't wish to upset anyone with a nagging problem that has previously been addressed. ![]() I really want to like it, but right now I simply can’t get around the difficulty of this tool for new beginners.First, I must state that I have spent hours researching this problem before finally deciding to register and post on this forum. There are almost NO articles or youtube videos that I’ve found that help with the tutorial lessons so I’m flying nearly blind with terrible instructions trying to learn a program that is supposed to be fantastic. I’m quickly getting fed up with this tool and wondering how anyone is supposed to learn how to model things in Fusion 360. When you do the coincidental tool (who picked THAT name), it won’t let you choose both pieces to match them up. When you attempt to select the equal sign tool for the two half circles, you can’t select them both. When you click the symmetric tool, and then click the two curved surfaces, it won’t make them symmetrical. The other two have not been mentioned yet, and this is the level of explanation they give to allow you to “learn”. Note the amount of explanation given, only the equal constraint has been explained at all. Add three constraints to the scissor blade profile: Symmetric constraint - the two inner flat edges of the scissor blades.Įqual constraint - the bottom of the scissor blade profile and the left side of the rectangular body.Ĭoincident constraint - the center points of these same two arcs. In step 5, it asks you to do the following:ĥ. Even Google isn’t really helpful in getting this figured out.įor instance, in the Adding Constraints and Dimensions exercise ( ), I finally figured out how to get the file needed (another thing not explained), but when you open it up, the pieces are in the “wrong” orientation. ![]() They state something BRAND NEW and then leave you hanging. Why do the tutorials NOT take you step by step through EVERYTHING. This weekend has been dedicated to learning Fusion 360. I’ve been spending quite a bit of time learning and liking Sketchup.
