content: I bought the CHM551 from Charmhigh and we will build our first board today. I wanted a machine that could handle 0201 components. The machine's performance has been amazing after practicing with the software, feeders, and calibration. I struggled with importing a CSV and aligning it to the machine coordinates. I fixed it using a spreadsheet that takes offset and angle and maps the entire x,y CAD space to the machine space. This requires one extra step but after my calibration, the location accuracy is almost perfect for the many 0201 components. If anybody wants to know how I did it, ask for a copy of the spreadsheet and a quick lesson. The spreadsheet solves the problem of an angle offset as just an X, Y offset is not good enough if the board is not perfectly square to the rails. A 1-degree error is bigger than an 0201 component across a small board.I will upload a video soon.I am hoping to connect with other users to share tips. I already learned a lot about Yamaha feeders from other postings.Thanks!

content: This was our first job, a densely populated sensor board with 320 2x2mm magnetometers, 700 0201 capacitors, and 12 1.8x1.2mm level shifters. We are still working out the kinks.https://youtu.be/-WsRD0_cJZQ

content: Thanks OP for sharing a short video. So this machine is only around 8K USD? I bought a desktop system with integrated feeders for about 5K two years ago but the prices have come down I guess. How much would you say you have to spend on shipping and feeders apart from the 8K machine price tag? It's unlikely I'll have space for this thing but to think of it, it's not much more space than my desktop machine but with 4 heads and automatic nozzle changing? Do they really provide service like they claim in their video, I mean on-site?

content: I have had a few problems with the pickup heads. They diagnosed one pretty quick, and sent a replacement solenoid, and it worked. The other issue related to some software setting and they sent a video on the process to recalibrate. So service has been pretty good for very remote via WhatsApp.

content: Hello,the CHM-551 looks like a good PnP Machine for us and i wanted to ask if everyone who bought it, is still happy with it?I also have a question regarding the ordering process of Charmhigh products. While researching I found different websites and email adresses for contact.One Contact is "sales@charmhigh-tech.com" and the other one is "sales@charmhigh.com". Right now i´m a bit confused, which one is the right/better one.Maybe the people who already bought it and see this postafter a year can help me with that question.Thanks in advanceBenjamin
